A select few: Several prochiral enyne chlorides were employed as substrates in the title reaction using Grignard reagents as the alkylation reagents (see scheme; CuTC=copper(I) thiophenecarboxylate). Excellent 1,3 substitution regioselectivities and good to excellent enantioselectivities were obtained. The substrate scope is additionally extended to diene chlorides.
少量选择:在标题反应中,使用格氏试剂作为烷基化试剂,使用了几种前手性烯属氯化物作为底物(参见方案; CuTC =噻吩铜(I)铜)。获得了极好的1,3取代区域选择性和良好至极好的对映选择性。底物的范围还扩展到二烯氯化物。
