diastereoselective synthesis of some branched functionalized homoallylic amine derivatives is described. The protocol starts with a 3,6-dihydrothiazine-1-oxide, which is readily obtained in a totally stereospecific manner by the hetero-Diels—Alder cycloaddition of an N-sulfinyl dienophile and a 1,3-diene. Various Grignard reagents have been added to these adducts to afford sulfoxide derivatives which
描述了一些支化的官能化均烯丙基胺衍生物的非对映选择性合成的新方法。该方案以3,6-二氢噻嗪-1-氧化物开始,该氧化物很容易通过N-亚磺酰基二烯亲和体和1,3-二烯的杂Diels-Alder环加成而以完全立体定向的方式获得。已将各种格氏试剂添加到这些加合物中以提供亚砜衍生物,其已通过[2,3]-或[3,3]-σ重排立体选择性地操作成支化的均烯丙基胺,可能对进一步的合成转化有用。
