摘 要:以(S)-2-氨基丙醇和(R)-2-氨基丙醇为手性源与α-溴代间氟苯丙酮反应,分别合成手性纯化合物(2R,3R,5S)-3,5-二甲基-2-(3-氟苯基)-2-吗啉醇盐酸盐(4A),(2S,3S,5R)-3,5-二甲基-2-(3-氟苯基)-2-吗啉醇盐酸盐(4B).利用X射线单晶解析仪测晶体结构和空间结构.化合物4A晶体属正交体系,空间群为P21212,晶胞参数a=8.6886(11)nm,b=20.059(2)nm,c=7.6052(8)nm,Z=4,V=1.3255(3)nm3,Dc=1.311 g/cm3,F(000)=552,R1=0.0257,wR2=0.0650,S=1.021.化合物4B属于正交体系,空间群为P21212,晶胞参数a=8.6887(9)nm,b=20.064(2)nm,c=7.6135(7)nm,Z=4,V=1.3272(3)nm3,Dc=1.310 g/cm3,F(000)=552,R1=0.0356,wR2=0.0653,S=1.Enantiopure compound (2R,3R,5S) -3 pholinol hydro- chloride (4A) and(2S ,3S ,SR) -3 ,5-dimethy-2-(3-fluorinephenyl) -2-mor- ,5-dimethy-2-(3-fluorinephenyl) -2-mor- pholinol hydrochloride (4B) was synthesized from ( S ) -2-amino-1 -propanol and 2-bromo- m-fluorinephenone, (R) -2-amino-l-propanol and 2-bromo-m-fluorine-phenone. Single-crys- tal X-ray analysis was used to measure crystal structure and space structure. The compound 4A crystal belongs to orthorhombic system with space group P21212 and cell parameters:a=8.6886(12) nm,b =20.059(3) nm,c=7.6052(9) nm, Z=4, V=1.3255(6) nm3, Dc =1.311 g/cm3, F(000) =552, R1 =0.0257, wRz =0.0650, S =1. 021. The com- pound 4B crystal belongs to orthorhombic system with space group P2x212 and cell param- eters:a =8.6887(9)nm, b=20.064(2) nm, c =7.6135(7) nm, Z=4, V=1.3272 (3) nm3, Dc =1.310 g/em3,F(000) =552, R1 =0.0356, wR2 =0.0653. S=1.033.
