The enynyl oxiranes (I) react with alkylsilver compounds to form butatrienyl carbinols RCH2C(Me)CCC(R′)CR″2OH (IV,V). Alkylcopper reagents, on the other hand, preferentially convert I into allenyl carbinols H2CC(Me)C(R)CC(R′)CR″2OH (III)
的环氧乙烷enynyl(I)与alkylsilver化合物形式丁三烯原醇反应RCH 2 C(Me)的CCC(R')CR“ 2 OH(IV,V)。烷基铜试剂,在另一方面,优选地转换到我丙二烯基原醇ħ 2 CC(ME)C(R)CC(R')CR“ 2 OH(III)
