the (inter)action: The interaction of alkoxides with the sp2 Bpin (pin=pinacol) moiety in aminoboranes forms the in situ Lewis acid–base adduct [RO−→B(OR)2N(R′)2] which enables the amino moiety to react as a strong nucleophile with several electrophiles, thus providing amino alcohols, β‐enamino esters, and β‐hydroxy amides in a direct and remarkably selective way (see scheme).
的(相互)动作的片:醇盐与SP的相互作用2 BPIN(引脚=频哪醇)部分在氨基硼烷形式原位路易斯酸-碱加合物[RO - →B(OR)2 N(R')2使氨基部分作为强亲核试剂与几种亲电试剂反应,从而以直接且显着选择性的方式提供氨基醇,β-烯氨基酯和β-羟基酰胺(请参见方案)。
