A facile and straightforward synthesis of cytogenin 1 (8-hydroxy-3-hydroxymethyl-6-methoxyisocoumarin) metabolite of Streptoverticillium eurocidicum and Certocystis fimbriata has been achieved. Condensation of chloroacetyl chloride with 3,5-dimethoxyhomophthalic acid 2 directly furnished 3-chloromethyl-6,8-dimethoxyisocoumarin 3 which was hydrolyzed to 6,8-dimethoxy-3-hydroxymethylisocoumarin 4 using
欧洲链霉菌和纤毛孢囊菌的细胞生成素1(8-羟基-3-羟甲基-6-甲氧基异香豆素)代谢物的简便,直接合成已实现。氯乙酰氯与3,5-二甲氧基高邻苯二甲酸2的缩合直接提供3-氯甲基-6,8-二甲氧基异香豆素3,使用0.05%氢氧化钠水溶液在THF中将其水解为6,8-二甲氧基-3-羟甲基异香豆素4。区域选择性脱甲基4产生细胞分裂素1。在模型实验中,制备了3-氯甲基异香豆素并将其转化为3-羟甲基异香豆素。
