The C1C28 portion of the cytotoxic natural product, amphidinolide B1 (1a), was synthesized enantioselectively using as key steps Evans chiral oxazolidinone chemistry, Sharpless asymmetric epoxidation, and the orthoester Claisen rearrangement. The overall yield is 3.6% in 13 step sequence starting from propionyl oxazolidinone 2.
使用Evans手性恶唑烷酮化学,Sharpless不对称环氧化和原酸酯Claisen重排作为关键步骤,对映选择性地合成了细胞毒性天然产物Amphidinolide B1(1a)的C1C28部分。从丙酰基恶唑烷酮2开始,在13个步骤中,总产率为3.6%。
