The reaction of N-methoxy-N-methylamides with the anion of ethyl 2-methoxy- , or 2,4-dimethoxy-6-methylbenzoate gives the corresponding ketones, which are cyclised to give the 3-substituted 8-methoxy- and 6,8-dimethoxy-isocoumarins in good overall yield.
N-甲氧基-N-甲基酰胺与2-甲氧基-乙基或2,4-二甲氧基-6-甲基苯甲酸根阴离子反应,生成相应的酮,这些酮环化后生成3-取代的8-甲氧基和6,8-二甲氧基异香豆素,总收率较高。
