Abstract
alpha,beta-Unsaturated dioxolanones derived from mandelic acid smoothl y add most Grignard reagents with good to excellent regio- and diaster eoselectivities. The adducts are converted to chiral secondary alcohol s by peroxidation at low temperature or to protected alpha-hydroxy ald ehydes via ozonolysis.
