enantioselective total synthesis of (+)-monomorine I (1) is described. The key feature of the synthesis is the asymmetric 1,3-dipolar cycloaddition of the prochiral nitrone 9 with the chiral (S)-allylic ether 8 as a dipolarophile, which provides stereoselectively the C-3,C-5-trans-isoxazolidine 10 with the correct relative and absolute stereochemistry suitable for the synthesis of (+)-monomorine I.
描述了(+)-单morine I(1)的对映选择性全合成。合成的关键特征是前手性硝酮9与手性(S)-烯丙基醚8作为双极性亲和剂的不对称1,3-偶极环加成反应,它立体选择性地提供了C-3,C-5-反-异恶唑烷10具有适合合成(+)-monomorine I的正确相对和绝对立体化学。
