甲酰基异长叶烯的合成新方法和产物的分离

A New Method of Synthesis of Formylisolongifolene and the Separation of Products

报道了由２羟甲基异长叶环烷和２羟甲基异长叶烯直接用过量１００％的铬酸溶液，于０℃，在氮气中进行反应的合成新方法．

Formylisolongifolic cycloalkanes and 2 formylisolongifolene are perfumery with a pronounced cedarwoodvetiver odour of great tenacity,and amber,clear sage dryout.This paper reports a new synthetic method by direct reaction of 2 hydroxymethylisolongifolic cycloalkanes,2 hydroxymethylisolongifolene and overdose 100% chromic acid solution at 0 ℃ in nitrogen.As well as describes the separate method of 2 formylisolongifolic cycloalkanes and 2 formylisolongifolene by means of step elution column chromatography.
