1,3-Cyclic sulfates (1b-d) participate in heterocyclisation reactions to give pyrrolidines (2b) and piperidines (2c/d). Cyclic sulfate activation, when coupled to the enantio- and diastereoselective generation of 1,3-diols, provides a synthesis of (+)-sedridine (9).
1,3-环硫酸盐(1b-d)参与杂环化反应,生成吡咯烷(2b)和哌啶(2c/d)。环状硫酸盐活化与对映体和非对映体选择性生成 1,3-二醇相结合,可合成 (+)-sedridine (9)。
