  The present invention provides stereoselective processes for the preparation of compounds of formula (I) wherein P is phenyl, naphthyl, a 6-membered heteroaryl group containing one or two nitrogen atoms as ring members, or a 10-membered bicyclic heteroaryl group containing one or two nitrogen atoms as ring members, and wherein the phenyl, naphthyl and heteroaryl groups are optionally substituted; R1 is chlorodifluoromethyl or trifluoromethyl; R2 is optionally substituted aryl or optionally substituted heteroaryl; n is 0 or 1; including the process comprising (a-i) reacting a compound of formula II wherein P, R1 and R2 are as defined for the compound of formula I; with nitromethane in the presence a chiral catalyst to give a compound of formula III Wherein P, R1 and R2 are as defined for the compound of formula I; and (a-ii) reductively cyclising the compound of formula III to give the compound of formula I. The invention also provides intermediates useful for processes for the synthesis of compounds of formula (I).

  本发明提供了立体选择性的制备式(I)化合物的方法，其中P是苯基、萘基、含有一个或两个氮原子作为环成员的6元杂环芳基基团或含有一个或两个氮原子作为环成员的10元双环杂环芳基基团，其中苯基、萘基和杂环芳基基团可选地被取代；R1是氯二氟甲基或三氟甲基；R2是可选地被取代的芳基或可选地被取代的杂环芳基；n为0或1；包括以下步骤的方法：(a-i)反应式II化合物，其中P、R1和R2如式(I)化合物所定义；与硝甲烷在手性催化剂的存在下反应，得到式III化合物，其中P、R1和R2如式(I)化合物所定义；以及(a-ii)还原环化式III化合物，得到式(I)化合物。本发明还提供了用于合成式(I)化合物的中间体。
