The present invention relates to a method for preparing piperidine derivative compounds by converting, with a piperidine compound, regioisomers having the formula:
and where m is an integer from 1 to 6; Q and Y are the same or different and are selected from the group consisting of O, S, and NR5; G1, G2, and G3 are the same or different and are selected from the group consisting of OR8, SR8, and NR8R9; R6 and R7 are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, an aryl moiety, OR8, SR8, and NR8R9; X3 is halogen, OR15, SR15, NR15R16, OSO2R15, or NHSO2R15; R5, R8, R9, R15, and R16 are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, and an aryl moiety; and A is a substituent of its ring and is selected from the group consisting of hydrogen, halogens, alkyl, hydroxy, alkoxy, and other substituents.
本发明涉及一种通过将带有以下式的吡啶衍生物化合物转化而制备吡啶衍生物的方法:其中m是1到6之间的整数;Q和Y相同或不同,选自O、S和NR5的群;G1、G2和G3相同或不同,选自OR8、SR8和NR8R9的群;R6和R7相同或不同,选自氢、烷基基团、芳基基团、OR8、SR8和NR8R9的群;X3是卤素、OR15、SR15、NR15R16、OSO2R15或NHSO2R15;R5、R8、R9、R15和R16相同或不同,选自氢、烷基基团和芳基基团的群;A是其环的取代基,选自氢、卤素、烷基、羟基、烷氧基和其他取代基的群。
