Scalable synthesis of enantiomerically pure syn -2,3-dihydroxybutyrate by sharpless asymmetric dihydroxylation of p -phenylbenzyl crotonate

An efficient four-step synthetic route to the useful chiral building block (2R,3S)-dihydroxybutyric acid acetonide in >95% ee is detailed. The sequence is readily scaled, requires no chromatography, and allows for efficient recycling of p-phenylbenzyl alcohol, an expedient for enantio- and diastereoenrichment by recrystallization.

Synthesis of (-)-Frontalin from the (2S,3R)-Diol prepared from α-Methylcinnamaldehyde and Fermenting Baker's Yeast

The synthesis of (-)-frontalin (13) from the (2S,3R)-diol (2b), through the intermediacy of the C5 (3S,4S) methyl ketone (6) and of the C11 adduct (8), is reported.
