摘要： A process for preparing 2,3-dihydroazepine compounds of general formula (1) or salts thereof inexpensively and simply, characterized by reacting a compound of general formula (2) or a salt thereof with a compound of general formula (3) or a salt thereof to form a compound of general formula (4) or a salt thereof and subjecting the obtained compound or salt to esterification and ring-closing reaction.

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 (I) or a salt thereof: {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-CH¿2?-Z is not -X?1-X2-CH¿2-Z (wherein X1 represents sulfur or optionally substituted nitrogen and X2 represents optionally substituted ethylene)]}, 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.

摘要： A process for preparing simply and inexpensively 2,3-dihydrothiepine derivatives represented by general formula (I) [wherein R1 is an electron-attracting group; R?2, R3, R4, R5, R6 and R7¿ are each hydrogen, halogeno, optionally substituted amino, optionally substituted hydroxyl, an optionally substituted thiol group, optionally substituted hydrocarbyl, or an optionally substituted heterocyclic group, or R?6 and R7¿ may be united to form a ring; and R8 is hydrogen or optionally substituted hydrocarbyl] or salts thereof, characterized by subjecting a compound represented by general formula (II) [wherein each symbol is as defined above] or a salt thereof to ring-closing reaction.
