资源简介:
A three-pot preparation of (S)-N-protected homoserine γ-lactones is presented. Conversion of N-protected l-aspartic acid to an oxazolidinone is followed by selective reduction/acid-catalyzed cyclization to deliver the lactones. Microwave irradiation proved valuable for improving the latter reaction steps in some cases.
