2-Methylcyclohexane-1,3-dione 14 was converted via the Wieland-Miescher analogue 15 into the 6-silyloxy-2,5,5,8a-tetramethyldecalin-1-one 21 by an efficient process. Several routes were examined to transform this compound into the pentacyclic triterpene s
Synthesis of 2-substituted 7-hydroxybenzofuran-4-carboxylates via addition of silyl enol ethers to o-benzoquinone esters
