摘要:
用配体调控策略,通过钯催化发展了乙烯基环状碳酰胺和异氰酸酯之间的两类差异性转化,选择性地合成了多取代的共轭二烯脲类化合物和四氢嘧啶酮衍生物.当反应以Pd2(dba)3·CHCl3(dba:dibenzylide...展开更多 用配体调控策略,通过钯催化发展了乙烯基环状碳酰胺和异氰酸酯之间的两类差异性转化,选择性地合成了多取代的共轭二烯脲类化合物和四氢嘧啶酮衍生物.当反应以Pd2(dba)3·CHCl3(dba:dibenzylideneacetone)为催化剂前体、以单齿配位的N,N-二甲基亚磷酰胺(Mono Phos)为配体时,可以高选择性地得到一系列线性的共轭二烯脲类衍生物;将配体改为双齿配位的1,3-双(二苯基膦)丙烷(DPPP)时,利用相同的原...
