摘要
从L-α-脯氨酸出发,经过酯化、N-烷基化、与格氏试剂反应合成了6个未见文献报道的(S)-(+)-N-取代吡咯烷甲醇衍生物3a~3f,其结构经IR,1HNMR和元素分析测定确证.并用X射线单晶衍射法测定了化合物(S)-(+)-1-[N-(5-氯-2-噻唑甲基)-2-吡咯烷基]-1,1-二苯基甲醇(3e)的晶体结构.晶体为单斜晶系,空间群为P2(1),a=0.8737(14)nm,b=0.9098(14)nm,c=1.2180(17)nm,α=90.00°,β=92.55(3)°,γ=90.00°,V=0.9671(3)nm3,Z=2,Dc=1.3217g/cm3,F(000)=404,R=0.0584,wR=0.1335.
Six unreported (S)-(+)-N-substituted pyrrolidinyl methanol deivatives 3a-3f were synthesized with L-a-proline as raw materials via esterification, N-alkylation and Grignard reaction. The structures of all newly synthesized compounds were elucidated and confirmed by elemental analysis, IR and 1H NMR spec- tra. The crystal structure of (S)-(+)-1-[N-(5-chloro-2-thiazolmethyl)pyrrolidin-2-yl]-1,1-diphenylmethanol (3e) was determined by X-ray diffraction analysis, which belongs to the monoclinic system, space group P2(1) with a=0.8737(14) nm, b=0.9098(14) nm, c =1.2180(17) nm, α= 90.00°, β=92.55(3)°,γ=90.00°, V=0.9671(3) nm3, Z=2, Dc= 1.3217 g/cm3, F(000) =404, R=0.0584, and wR=0.1335.
