Abstract
Abstract An efficient synthesis of 2-azido-3-hydroxy-1, 4-diones, based on the base-induced coupling of α-azido ketones and α-oxo aldehydes, has been developed. The coupling reaction took place with moderate to good diastereoselectivity. The relative configurations of the adducts have been determined by X-ray analysis. Treatment of tetrafunctionalized synthons 2-azido-3-hydroxy-1, 4-diones with mesyl chloride in the presence of base ...
