Stereoselective synthesis of boronolide and 5-epi-boronolide was achieved from d-(−)-tartaric acid. The key step involves the reduction of a keto Weinreb amide for the synthesis of boronolide, and a single pot construction of a diketone from the bis-Weinreb amide of tartaric acid and subsequent reduction with L-Selectride for 5-epi-boronolide.
由d-(-)-酒石酸实现了硼烷内酯和5-表-硼烷内酯的立体选择性合成。关键步骤包括还原用于合成硼烷内酯的酮威因雷伯酰胺,以及由酒石酸的双-Weinreb酰胺单锅构建二酮,随后用L-Selectride还原5-表-硼烷内酯。
