The acetylcholinesterase inhibition by enantiomers of exo‐ and endo‐2‐norbornyl‐N‐n‐butylcarbamates shows high stereoselelectivity. For the acetylcholinesterase inhibitions by (R)‐(+)‐ and (S)‐(−)‐exo‐2‐norbornyl‐N‐n‐butylcarbamates, the R‐enantiomer is more potent than the S‐enantiomer. But, for the acetylcholinesterase inhibitions by (R)‐(+)‐ and (S)‐(−)‐endo‐2‐norbornyl‐N‐n‐butylcarbamates, the
Exo-和endo -2-降冰片基-N - n-丁基氨基甲酸酯的对映异构体对乙酰胆碱酯酶的抑制作用显示出高立体选择性。对于(R)-(+)-和(S)-(-)- exo -2-降冰片基N - n-丁基氨基甲酸酯的乙酰胆碱酯酶抑制作用,R对映体比S对映体更有效。但是,对于由(乙酰胆碱酯酶的抑制- [R )- (+) -和(小号) - ( - ) -内型-2- norbornyl- ñ - Ñ -butylcarbamates,该小号对映体比R对映体更有效。光学纯的(R)-(+)- exo - ,(S)-(-)- exo -,(R)-(+)-内消旋-和(S)-(-)-内消旋-2-降冰片基- ñ - ñ -butylcarbamates从光学纯(的缩合合成- [R(+) - - )外切,(小号) - ( - ) -外- ,(- [R )- (+) -内切-和(小号) - (−)‐内基-2-降冰片醇,
