Mandelic and lacticacids are converted to the 1,3-dioxolan-4-ones by treatment with acetone dimethyl acetal. Deprotonation followed by treatment with an allyl acetate and a catalytic amount (1 mol %) of palladium catalyst afforded the allylated dioxolanones, which could be hydrolyzed to the corresponding α-allyl α-hydroxy acids. The lithium enolate of the dioxolanone of mandelic acid was also coupled

日期:——
The reaction of acetonides of α-hydroxycarboxylic acids with primary amines on heating provides a useful synthetic route to N-substituted α-hydroxycarboxamides. In general, formation of the α-hydroxycarboxamides is favored by the presence of only small substituents on the acetonide, by sufficient nucleophilicity of the amine, and by high-boiling aprotic solvents.

The 1,3-dioxolan-4-ones readily derived from α-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 β-methyl-γ-oxo esters and by using chiral dioxolanones these can be obtained in up to 86% e.e.
