    • The present invention relates to a process for preparing a compound of Formula (Vl), wherein R1 and R6 are hydrogen, substituted or unsubstituted alkyl substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; R5 is OR2, NR2R3, SR2, B (OR2)(OR3), or X" selected from F, Cl, Br, I, OCOR2, OSO2R2, wherein R2 and R3 independently from each other represent substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; or R2 and R3 cooperatively form a part of a 5- to 10-membered fused or unfused ring, optionally a chiral 5- to 10- membered fused or unfused ring; X is selected from F1 Cl, Br, I; and * indicates a chiral center; by hydrogenation of a compound of Formula (V), wherein R1, R5, R6 and X are as defined above; wherein hydrogenation is conducted in the presence of a catalyst selected from complexes comprising at least one transition metal, wherein dehalogenation occurs in less than 10 molar % relative to the molar amount of the compound of formula Vl.
    • 本发明涉及制备式(VI)化合物的方法,其中R 1和R 6是氢,取代或未取代的烷基取代或未取代的芳基或取代或未取代的芳烷基; R5是选自F,Cl,Br,I,OCOR2,OSO2R2中的OR2,NR2R3,SR2,B(OR2)(OR3)或X“,其中R2和R3彼此独立地表示取代或未取代的烷基,取代或未取代的 芳基或取代或未取代的芳烷基;或R 2和R 3协同形成5至10元稠合或未稠合的环的一部分,任选的手性5-至10-元稠合或未稠合的环; X选自F1 C1, Br,I和*表示手性中心;通过氢化式(V)的化合物,其中R 1,R 5,R 6和X如上所定义;其中氢化在催化剂存在下进行,所述催化剂选自: 至少一种过渡金属,其中相对于式VI化合物的摩尔量,脱卤发生在小于10摩尔%的范围内。
