important antimalarial drug. It is currently manufactured and administered in racemic form; however there are indications regarding the biological activity of the two enantiomers that suggest the superiority of the (+)-form. The asymmetric total synthesis of the (+)-enantiomer of mefloquine hydrochloride is described. The key asymmetric transformation utilized is a novel asymmetric Darzens reaction of
盐酸甲氟喹是一种重要的抗疟药。目前以消旋形式生产和管理。然而,关于两种对映异构体的生物活性的迹象表明(+)-形式的优越性。描述了盐酸甲氟喹的(+)-对映异构体的不对称全合成。所利用的关键的不对称转化是衍生自N-氨基环状氨基甲酸酯(ACC)手性助剂的手性α-氯-N-氨基环状氨基甲酸酯的新型不对称Darzens反应。
