The amide group of 2-acyl-N,N-dialkyl-1-naphthamides, twisted perpendicular to the naphthyl ring, controls the stereoselectivity of attack of nucleophiles on the 2-substituent. Selectivities of >140:1 may be achieved with bulky nucleophiles, which attack anti to the N,N-dialkyl group.
垂直于萘基环扭曲的2-酰基-N,N-二烷基-1-萘酰胺的酰胺基控制亲核试剂攻击2-取代基的立体选择性。的> 140选择性:1可与亲核试剂笨重,其攻击来实现抗到Ñ,Ñ二烷基团。
