    摘要： 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 and 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.
