The conformation in solution of 1-phenyl-3-propionamido-1,2,3,4-tetrahydronaphthalene and 1-phenyl-3-(N,N-dimethylamino)-1,2,3,4-tetrahydronaphthalene has been determined by a combination of nuclear magnetic resonance measurements and molecular mechanics calculations. The results indicate that in the cis isomers the cyclohexene ring is in a locked conformation and the trans isomers correspond to a
1-苯基-3-丙酰胺基-1,2,3,4-四氢萘和1-苯基-3-(N,N-二甲基氨基)-1,2,3,4-四氢萘在溶液中的构象已通过结合了核磁共振测量和分子力学计算。结果表明,在顺式异构体中,环己烯环处于锁定构象,而反式异构体对应于两个倒置的半椅子的混合物。此外,该数据允许鉴定1-苯基-3-丙酰胺基四氢萘的两种目的合成的几何异构体。对褪黑激素受体亚型的结合研究表明,(+/-)-顺-1-苯基-3-丙酰胺基-1,2,3,4-四氢萘对MT(2)亚型的亲和力和选择性比( +/-)-反式异构体。
