Abstract

The title reactions of sterically crowded 2-oxazolidone derivatives with achiral aldehydes in the presence of zinc dust were found to give various 2,3-syn-aldols as major products (at most, 2,3-syn:2,3-anti=98:2). While a 2,3-syn-3,4-syn-aldol could be similarly produced in a highly stereoselective manner, application of the explored reaction to asymmetric synthesis of optically active 2,3-syn-aldols was found to be unpromising.
