Stereoselective cycloaddition of N-acyliminium cations withα,β-unsaturated ketones and esters

The cycloaddition of N-acyliminium cations with some deactivated alkenes such as α,β-unsaturate ketones and esters has been investigated. In most cases, the N-acyliminium cations produced from 3-hydroxy-2-arylisoindol-1-ones in the presence of BFa.OEt2 could be reacted with α,β-unsaturated ketones and esters to afford stereoselectively the cycloaddition products 6-acylisoindolo[2,1- a]quinolin-11-ones in moderate to high yields.

浅谈替代词it,one,ones,that,those

Stereoselective Synthesis of 2-Chloro-4-Substituted-phenyl-5,5-Dimethyl-1,3,2-Dioxaphosphorinan-2-(Thi)ones

The stereoselective synthesis of 2-chloro-4-substituted-phenyl-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-(thi)ones is described. Only single trans-isomers were obtained when 1-substituted-phenyl-2,2-dimethyl-1,3-propanediols (1) reacted with POCl3. But the stereoselectivity of cyclization reaction between (1) and PSCl3 depended greatly upon the reaction condition. The configurational assignments and the ratio of cis-/trans- diastereoisomers of the products were performed on the basis of (HNMR)-H-1, (PNMR)-P-31 and IR spectra and confirmed by X-ray diffraction analyses.

How Long Can Chinese Enterprises Become Famous Transnational Ones

Entry into WTO means that Chinese enterprises, which were deeply influenced by planned economy, will scramble for profits with those world famous transnational companies of strong strength. Facing such competitive situation, how can China cultivate more famous and strong Chinese transnational companies on the international market? This is a question for many economists and enterprisers to make serious research.

A New Solution-phase Parallel Synthesis of 2-Alkylamino-3-aryl-5-phenylmethylene-3,5-dihydro-4H-imidazol-4-ones

Thirteen new 2 alkylaminoimidazolones (4) were rapidly synthesized by a new solution phase parallel synthetic method, which includes aza Wittig reaction of iminophosphorane (1) with aromatic isocyanate to give carbodi imide (2) and subsequent reaction of 2 with various aliphatic primary amine in a parallel fashion. The products were confirmed by 1H NMR, MS, IR and X ray crystallographic analysis. The unusual selectivity of the cyclization was probably due to the geometry of the guanidine intermediate.

THE MORPHOLOGICAL SIMILARITY AND SYMMETRY OF NEURONES IN THE LEECH Whitmania pigra

Using the method of intracellular injection of horseradish peroxidase, the arborizations of several neurones with different functions in the segmental ganglia of the leech Whitmania pigra are investigated. Comparison is made in each kind of neurones in order to verify their typical pattern. Results show that the morphology of the axonal arbors of identified neurones has an accurate similarity within and among the individuals of the leech, and the axonal arborizations of the bilaterally identified neurones in the same ganglion have a stable symmetry. The possible reasons of the formation and its functional significance of the symmetrical nervous system are discussed.

风水林探源与当代启示(英文)

Origin of Fengshui Woods was studied, 3 representative standpoints (Fengshui doctrines, greening and worship of the god of land) about Fengshui woods were analyzed, and worship of the god of land was believed as a reasonable origin view through considering natural and social factors of ancient China, as well as universal mental characteristics of people in the prescience age. To identify advantages and disadvantages of these 3 views, Carl G. Jung' theory of mythological prototype criticism and Sir James George Frazer's anthropological study were borrowed to prove that Fengshui Woods originated from ancient Chinese worship of the god of land, and such worship gradually evolved into practices of planting Fengshui Woods for their propitious signs. On this basis, enlightenment of Fengshui Woods to modern society was disclosed to protect present Fengshui Woods and forest resources.

How to Get Along with Others

In our daily life,we can’t avoid associating with people in the world,so it is important for us to know how to get along with others.In my opinion,to get along with others,we must remember the following advices①.First,we need to be honest with others.Telling lies surely makes people stay far away from you.Just as an old saying goes,"Honesty is the best policy."Second,we should be modest enough.If we are proud in public,we can hardly win others②respect.Finally,we shouldn’t be selfish.We should learn to share.

Study on Landscape Features of Bai People'sTraditional Mountainous Villages in Dali

In view of the vast mountainous areas and abundant mountainous settlement resources of Dali Bai Nationality Autonomous Prefecture, the authors proposed the significance and necessity of studying landscape features of traditional mountainous settlements of the Bai Nationality by considering policy requirements of "protection system planning of famous historic and cultural cities, towns, villages and blocks in Yunnan Province" and "construction of mountainous towns". On the basis of investigating traditional mountainous settlements of the Bai Nationality in Dali, 5 typical settlements were analyzed from the perspectives of landscape structure, village layout, landscape element, landscape materials and decorative art. And characteristics of traditional mountainous settlements of the Bai Nationality were summarized as "following the nature, adaptive to actual terrains, multidimensional, human-nature oneness".

Application of Fengshui Doctrines in Landscape Architecture Design

Proceeding from the concept of Fengshui, the author focused on the influence of Fengshui on construction activities in ancient China, and proposed that Fengshui has impacted not only site selection and layout of ancient cities, towns, villages, palaces and residences, but also site selection and layout of classical Chinese gardens. On this basis, application of Fengshui in modern landscape architecture design was explored, and the harmony between garden planning and environment factors was stressed, and also psychological factors of human beings emphasized. In this way, the doctrine of "human-nature oneness" was demonstrated, spirit of place and actual conditions of the planning site respected, and propitious culture manifested.

Application of Chinese Landscape Painting Ambience in Modern Residential Landscape

Planning and design of modern residential landscapes in China has experienced rapid growth, but many residential areas have simulated western landscape designs and lost the ambience of traditional Chinese landscape painting, and the designs have shown poor diversity, artistic quality or unification of landscapes and environmental effects. Hence, the paper proposed that modern residential landscape design should be integrated with Chinese landscape painting factors, and the concept of "human-nature oneness" should be demonstrated to create garden landscapes suitable for appreciating, sightseeing, living and enjoying, and also living spaces with picturesque scenery. Through analyzing landscape designs of "Century Sunshine Garden" in Hefei City, Anhui Province, the study explored the integration of modern residential landscapes and Chinese landscape painting ambience, so as to create green, ecological, healthy, practical landscapes for modern residential areas.
