A method for the preparation of β-amino alcohol of formula (III) in which R1 is Ph, (substituted) Ph, R2 is C1-8 alkyl or C4-6 cyclo alkyl, R3 = R4R5CHNH2 where, R4 = H, C1-8 alkyl, C4-6 cyclo alkyl, or - COOR6 (R6=C1-C8 alkyl); R5 = (subst) aryl], the method including subjecting an α-hydroxy ketone of formula (I) in which R1 and R2 are as defined above is reacted with a chiral amine of formula R3NH2 where R3 = R4R5CH- where, R4 = H, C1-8 alkyl, C4-6 cycloalkyl, or - COOR6 (R6=C1-8 alkyl), R5 = (subst) aryl] to produce a compound of formula (II) in which R1, R2 and R3 are as defined above, followed by reduction to form the compound of formula (III).
一种制备β-氨基醇的方法,其化学式为(III),其中R1为苯基、(取代)苯基,R2为C1-8烷基或C4-6环烷基,R3 = R4R5CHNH2,其中,R4 = H、C1-8烷基、C4-6环烷基或-COOR6 (R6=C1-C8烷基);R5 = (取代)芳基]。该方法包括将化学式为(I)的α-羟基酮,其中R1和R2如上定义,与具有化学式R3NH2的手性胺反应,其中R3 = R4R5CH-,其中,R4 = H、C1-8烷基、C4-6环烷基或-COOR6 (R6=C1-8烷基),R5 = (取代)芳基],以生成化学式为(II)的化合物,其中R1、R2和R3如上定义,随后还包括还原以形成化学式为(III)的化合物。
