A chiral catalyst prepared from N,N′-dioxide and Co(BF4)2·6H2O was applied in the asymmetric hydride transfer initiated cyclization reaction, giving optically active tetrahydroquinolines in good yields with high enantioselectivities under mild reaction conditions. Meanwhile, in light of the absolute configuration of the product, a possible working model was proposed to explain the origin of the activation
将由N,N'-二氧化物和Co(BF 4)2 ·6H 2 O制备的手性催化剂用于不对称
氢化物转移引发的环化反应中,在温和的反应条件下,以高收率和高对映选择性得到旋光性
四氢喹啉。同时,根据产品的绝对配置,提出了可能的工作模型来解释激活和不对称感应的起源。
