摘要:
The synthesis of 1-vinyl-1-methyl-3-chloromethylcyclohex-3-ene from 3-vinyl-3-methylcyclohexanone and the corresponding exomethylene derivative has been optimized and related allylsulfones prepared. By a standard combination of these compounds with the appropriate (cyclo)geranyl block synthones a series of regular functionalized diterpenoids has been prepared which are considered as likely precursors of the natural compounds indicated in the title.
