    An esculetin compound, an intermediate thereof, a process for manufacturing an esculetin compound, and an antifungal composition for agriculture and horticulture and an herbicide comprising an esculetin compound or an intermediate thereof are provided. The process for manufacturing an esculetin compound is a low-cost, high-yield, and industrially practicable process, and comprises the following step. A process for manufacturing an esculetin compound of the formula (2): characterized by cyclizing a trihydroxybenzaldehyde compound of the formula (1): in an aprotic polar solvent in the presence of a weak base, with acetic anhydride or the like.
    提供了一种香豆素化合物、其中间体、制造香豆素化合物的方法,以及用于农业和园艺的抗真菌组合物和包含香豆素化合物或其中间体的除草剂。制造香豆素化合物的方法是一种低成本、高产率且工业可行的方法,包括以下步骤。制造化合物的过程是通过在无极性溶剂中的弱碱存在下使式(1)的三羟基苯甲醛化合物环化,使用乙酸酐等。

    Reaction of salicylaldehydes (1) with carbethoxymethylenephosphorane in diethylaniline under reflux gave coumarins (3) in excellent vields. Methoxy substituent at C4 on salicylaldehyde (1) facilitated the formation of coumarin from trans-cinnamate (2), which is first prepared by reaction of 1 with Wittng reagent.

    In connection with studies on the structure elucidation of the so-called Reisch's coumarin isolated from Toddalia asiatica, syntheses of two coumarins (4 and 5) were accomplished via the routes shown in Charts 2 and 3, respectively. Melting points and NMR data of the synthesized coumarins (4 and 5) and of related coumarins (5-methoxysuberenon, toddalenone, and Reisch's coumarin) are given in Table I, suggesting that so-called Reisch's coumarin might be 4.
