PROCESS FOR PRODUCTION OF DIALCOHOL, PROCESS FOR PRODUCTION OF ALLYLHALIDE COMPOUND, AND ALLYLCHLORIDE COMPOUND |
摘要 |
Disclosed are: an advantageous production process for a carotenoid intermediate; and others. Specifically disclosed are: a process for producing a dialcohol represented by formula (1), which is characterized by reacting a Grignard reagent with an acetylene gas in an organic solvent at a temperature of 30° C. or higher to prepare an ethynyl magnesium halide and subsequently reacting the ethynyl magnesium halide with methacrolein; a process for producing an allylhalide compound represented by formula (3) [wherein X represents a halogen atom: and the wavy line means the compound is either of E/Z geometric isomers or a mixture thereof], which is characterized by reducing a dialcohol represented by formula (1) with hydrogen to produce a triene alcohol represented by formula (2) [wherein the wavy line is as defined above] and halogenating the triene alcohol; and an allylchloride compound represented by formula (4) [wherein the wavy line is as defined above].
