摘要：

A variety of 2-oxazolidinones are prepared in good to excellent yields by the organotin alkoxide promoted ring cleavage of γ-bromo β-lactones. This reaction proceeds via the key organotin haloalkoxide intermediate, which reacts with an isocyanate followed by cyclization. Stereoisomerically pure products are obtained by combination with the stereoselective bromolactonization reaction. Moreover, other heterocumulenes such as RN=C=NR, RN=C=S, C02, and γ-bromo β-lactam are used as substrates. © 1990, American Chemical Society. All rights reserved.
