    摘要: A method including resolution of a diastereomeric mixture represented by the formula wherein R1 and R2 are the same or different and each is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, only one of R1 and R2 contains one asymmetric carbon, and Ra is an optically active and optionally substituted hydrocarbon group or an optically active and optionally substituted heterocyclic group, or a salt thereof, to produce the diastereomer having a steric configuration of the asymmetric carbon for R1 or R2 of an R configuration or an S configuration, or a salt thereof.

    摘要: A process suitable for safely mass-producing, through a short step, cyclic compounds useful in medicines, agricultural chemicals, foods, cosmetics, and chemical products or as intermediates therefor. The process, which is for producing a compound represented by the formula: {wherein Z represents an electron-attracting group; W represents optionally substituted ethylene or optionally substituted vinylene; R3 represents hydrogen or an optionally substituted hydrocarbon group; and X represents a divalent group [provided that when W represents optionally substituted vinylene, then —X—CH2-Z is not —X1—X2—CH2, -Z (wherein X1 represents sulfur or optionally substituted nitrogen and X2 represents optionally substituted ethylene)]} or a salt thereof, is characterized by subjecting a compound represented by the formula (II) or a salt thereof: (wherein the symbols have the same meanings as the above) to a ring closure reaction in a solvent containing a carbonic diester.
