Optically active fluorine-containing alcohols with up to 97% enantiomeric excess were synthesized by the enantioselective addition of dialkylzincs to fluorine-containing aldehydes using chiral β-aminoalcohol catalysts such as N,N-dibutylnorephedrine (DBNE, 2d), 2-morpholino-1-phenyl-1-propanol (2g, MOPEP) and diphenyl(1-methylpyrrolidin-2-yl)methanol (3, DPMPM).
通过使用手性β-氨基醇催化剂(例如N,N-二丁基去氧麻黄碱(DBNE,2d),2-吗啉代-1)将二烷基锌向含氟醛中对映选择性加成,合成了对映体过量高达97%的旋光含氟醇。-苯基-1-丙醇(2g,MOPEP)和二苯基(1-甲基吡咯烷-2-基)甲醇(3,DPMPM)。
