way of olefin cross-metathesis in eight to nine steps and in an overall yield of 19% to 26% from 2,3,4-tri-O-benzyl-d-xylopyranose. Optimization of cleavage conditions of N-NAP-protected tertiary amines using DDQ in CH2Cl2-H2O (18:1) is also reported. The iminosugars synthesized will be used as key building blocks in the synthesis of multivalent iminosugars of biological interest by way of Cu(I)-catalyzed
叠氮化物-武装α-1- Ç -烷基-亚氨基- d -木糖醇衍生物已通过烯烃交叉复分解的方式被有效地制备在八至九的步骤和在19%,从2,3,4-总收率26%三- ø苄基d -xylopyranose。还报道了使用DDQ在CH 2 Cl 2 -H 2 O(18:1)中优化N -NAP保护的叔胺的裂解条件。合成的亚氨基糖将通过Cu(I)催化的叠氮化物-炔烃环加成反应,被用作生物感兴趣的多价亚氨基糖合成的关键组成部分。
