A straightforward concise synthesis of chiral non-racemic aliphatic α-boryl isocyanides, relay intermediates for boron-based bioactive molecules in multicomponent reactions, is presented. The short synthetic sequence comprises as key steps copper-catalysed asymmetric borylation of imines, simultaneous nitrogen formylation/boron-protecting group interconversion and the final formamide dehydration reaction
介绍了手性非外消旋脂肪族 α-硼基异氰化物的直接简明合成,这是多组分反应中硼基生物活性分子的中继中间体。短合成序列包括作为关键步骤的铜催化亚胺的不对称硼基化、同时氮甲酰化/硼保护基团相互转化和最终的甲酰胺脱水反应。
