The new domino process disclosed here involves PBu3 as both a nucleophilic and a reducing agent. The process combines suitable electron-poor dienes, N-tosylimines, tri-n-butylphosphane and water. The final products formally result from reduction of vinylogous aza-Morita–Baylis–Hillman adducts. The reaction proceeds with an excellent stereochemical control of the relative configurations of the newly
这里公开的新多米诺过程涉及 PBu3 作为亲核剂和还原剂。该方法结合了合适的缺电子二烯、N-甲苯磺酰亚胺、三正丁基膦和水。最终产品正式来自减少乙烯基氮杂-森田-Baylis-Hillman 加合物。该反应在对新创建的连续碳中心的相对构型进行出色的立体化学控制的情况下进行。
