The first synthesis of cremeomycin (3-diazo-4-methoxy- 2-oxocyclohexa-4,6-dienecarboxylic acid), a naturally occurring diazocarbonyl compound, is described. Starting from methyl 2-hy- droxy-4-methoxybenzoate, nitration, hydrolysis, and reduction gave 3-amino-2-hydroxy-4-methoxybenzoic acid as the key ami- nophenol precursor, diazotization of which gave the diazoquinone natural product.
描述了克瑞霉素(3-重氮-4-甲氧基-2-氧代环己-4,6-二烯羧酸)的首次合成,一种天然存在的重氮羰基化合物。从 2-羟基-4-甲氧基苯甲酸甲酯开始,经硝化、水解和还原得到 3-氨基-2-羟基-4-甲氧基苯甲酸作为关键的氨基苯酚前体,其重氮化得到重氮醌天然产物。
