フォスファゼン塩基触媒を用いる置換アルキルケイ素化合物の変換反応

抄録

The catalytic activation of C-Si and O-Si bond by t-Bu-P4 base has been investigated and the present study focused on the activation of C-Si bond of ethyl trimethylsilylacetate. The reaction with benzophenone in the presence of catalytic amount of t-Bu-P4 base proceeded at -78°Cto give the unsaturated carboxylate in excellent yield. This Peterson type olefination was applied for the synthesis of enaminoesters using N-alkylformanilide as substrates. The scope and limitation of these transformations were investigated.
