A process for stereoselective synthesis of compounds of Formula (X) wherein: R1 is an aryl or heteroaryl group, each optionally independently substituted with one to three substituent groups, wherein each substituent group of R1 is independently C1-C5 alkyl, C2-C5 alkenyl, C2-C5 alkynyl, C3-C8 cycloalkyl, heterocyclyl, aryl, heteroaryl, C1-C5 alkoxy, C2-C5 alkenyloxy, C2-C5 alkynyloxy, aryloxy, C1-C5 alkanoyloxy, C1-C5 alkanoyl, aroyl, trifluoromethyl, trifluoromethoxy, or C1-C5 alkylthio, wherein each substituent group of R1 is optionally independently substituted with one to three substituent groups selected from methyl, methoxy, fluoro, chloro, hydroxy, oxo, cyano, or amino; and R2 an R3 are each independently hydrogen or C1-C5 alkyl, or R2 and R3 together with the carbon atom they are commonly attached to form a C3-C8 spiro cycloalkyl ring.
一种用于立体选择性合成Formula(X)化合物的方法,其中:R1是芳基或杂环芳基,每个可以独立地用一个到三个取代基取代,其中R1的每个取代基可以独立地是C1-C5烷基、C2-C5烯基、C2-C5炔基、C3-C8环烷基、杂环烷基、芳基、杂环芳基、C1-C5烷氧基、C2-C5烯氧基、C2-C5炔氧基、芳氧基、C1-C5酰氧基、C1-C5酰基、芳酰基、三氟甲基、三氟甲氧基或C1-C5烷基硫基,其中R1的每个取代基可以可选地独立地用来自甲基、甲氧基、氟、氯、羟基、羰基、氰基或氨基的一个到三个取代基取代;而R2和R3分别独立地是氢或C1-C5烷基,或者R2和R3连同它们共同连接的碳原子形成一个C3-C8螺环烷基环。
