    摘要： There is described a process for the preparation of compounds of formula I
    in which

    R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and
    R 1 and R 2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms,
    which comprises reacting a compound of formula II
    with a compound of formula III
    in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.

    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].
