One pot, many reactions! The reaction of two equivalents of ethyl(2‐bromomethyl)acrylate with dinitroalkanes (see scheme) leads to the one‐pot, diastereoselective synthesis of a variety of polyfunctionalized bicyclo[3.3.1]nonanes in very good overall yields. The reaction proceeds through an anionic domino process, with the in situ generation of four new CC bonds.
一锅多反应!两当量的(2-溴甲基)丙烯酸乙酯与二硝基烷烃的反应(见方案)导致以非常好的总产率单锅、非对映选择性合成各种多官能化双环[3.3.1]壬烷。该反应通过阴离子多米诺骨牌过程进行,原位生成四个新的 C C 键。
