scope of the Prins cyclisation, the higher stereoselective synthesis of multisubstituted tetrahydropyrans from aldehydes and homoallylic alcohols, is expanded. A new approach for the stereoselective synthesis of polyketide precursors containing anti-1,3-diols, flanked by a variety of alkyl branches and functional groups is described. The approach is successfully exploited for the synthesis of (−)-sedamine
Prins环化的范围得到了扩展,这是由醛和均烯丙基醇进行的多取代四氢吡喃的更高立体选择性合成。描述了一种立体选择性合成含有抗-1,3-二醇的侧接各种烷基分支和官能团的聚酮化合物前体的新方法。该方法已成功地用于合成(-)-sedamine。
