Add to ORKGThe 1,3-dioxolan-4-ones readily derived from alpha-hydroxy acids act as convenient acyl anion equivalents by deprotonation - alkylation Followed by flash vacuum pyrolysis. Conjugate addition of their anions to ethyl crotonate similarly gives beta-methyl-gamma-oxo esters and by using chiral dioxolanones these can be obtained in up to 86% e.e.</p
