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

ABSTRACT: 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.
