A zinc enamide generated from the corresponding N-aryl imine undergoes addition to an unactivatedolefin, such as ethylene, 1-octene, and isobutylene, to generate an alpha-alkylated gamma-zincioimine intermediate in good to excellent yield. Terminal and gem-disubstituted olefins react with >99% regioselectivity, allowing the C-C bond formation to take place at the more hindered carbon of the double
由相应的 N-芳基亚胺生成的锌烯酰胺与未活化的烯烃(例如乙烯、1-辛烯和异丁烯)加成,以良好至极好的收率生成 α-烷基化 γ-锌亚胺中间体。末端和偕二取代的烯烃以>99% 的区域选择性反应,使得 CC 键的形成发生在双键的受阻更大的碳上。有机锌中间体与碳亲电子试剂进一步形成 CC 键,在亚胺水解后,生成带有各种官能化伯、仲和叔烷基的 α-烷基化酮。

A procedure is described for the preparation of highlybranchedketones and alcohols with the general formulae R2R3R4C·CHR5·CO·R1 and R2R3R4C·CHR5·CR6(OH)R1. The multi-step route involves classical synthetic methods which give good yields. R may be varied and can be either alkyl or aryl.
描述了制备通式为R 2 R 3 R 4 C·CHR 5 ·CO·R 1和R 2 R 3 R 4 C·CHR 5 ·CR 6(OH)R的高度支化的酮和醇的方法1。多步路线涉及经典的合成方法,可提供良好的收率。R可以变化并且可以是烷基或芳基。
