Abstract
The synthesis of 10-methoxycarbonyl-1,7,7-trimethyl-cis-2-decaIone (6c) is described as well as that of the corresponding trans isomer. The stereochemistry of catalytic hydrogenation of the carbon–carbon double bond of Δ1,9-2-octalones is shown to be controlled by the angular substituent at position 10.The cis-decalin system is considered as a synthon for the DE ring system of certain pentacyclic triterpenes.This publication has 0 references indexed in Scilit:
