Biosynthesis of indole diterpenes, emindole, and paxilline: Involvement of a common intermediate

, p. 2697 - 2700 (2004)
The key step for construction of the carbon skeleton in the indole diterpenes, paxilline, and emindole DA was examined. Intact incorporation of multiply 2H-labeled 3-geranylgeranylindole into two different fungal metabolites proves 3-geranylgeranylindole to be a biosynthetic intermediate. These results give evidence that indole diterpenes are biosynthesized via epoxidation of a common intermediate, and the subsequent cationic cyclization, analogous to those in the steroid biosynthesis.
Preparation method of vitamin A and vitamin A ester
-
Paragraph 0065; 0067; 0073; 0075, (2020/04/02)
The invention provides a novel method for preparing vitamin A and vitamin A ester with farnesene as a raw material. The method comprises the following steps: reacting farnesene with acetoacetate underthe action of a catalyst to obtain farnesyl keto ester; carrying out a cyclization reaction and a dehydrogenation reaction on farnesene acetone, and then reacting a reaction product with vinyl magnesium halide to generate vinyl alcohol; carrying out a rearrangement reaction on vinyl alcohol to obtain vitamin A; and subjecting the vitamin A to an esterification reaction to obtain the vitamin A ester. The method avoids the defects of the existing processes, and the process line of the method is economical and effective.
