Tetrahydrofolate (THF) coenzymes are involved in biochemical transfer of aone-carbon fragment at different oxidation levels. The study of THF models may providea valuable class of reagents for group transfer reactions with practical significance. Onlya few researches about 5, 10-methenyl-THF models have been reported in literature. 展开更多

Four 1, 2, 3-trisubstituted imidazolinium iodides which were used as 5,10-^+CPh-THF model (7-10) at formic acid oxidation level were synthesized. The benzylidyne group (phenyl- substituted one carbon unit)transfer reactions from these compounds to Grignard reagent were in- vestigated, and the reactions of these compounds with KBH_4 and NaOH were also studied. 展开更多

Mannich bases can be either directly employed or used as intermediates. In this work, the one-carbon unit transfer reaction of tetrahydrofolate coenzyme was initiated. 1,3-Dimethylimidazolidine as a new tetrahydrofolate coenzyme model at formaldehyde oxidation level was used to react with ketone having active hydrogen atoms and amine to give the corresponding Mannich base in good yield by a covert Mannich reaction. A novel method for biomimetic synthesis of various Mannich bases is provided. 展开更多
