N-Hydroxy-4-oxoquinazoline-2-carboxamide derivatives (cyclic hydroxamic acids) and related pyrido- and thieno-substituted analogues, as well as a N-hydroxyhypoxanthine-2-carboxamide were synthesised for the first time, by means of a four-step sequence that involves a smooth reaction of aminohydroxamates with methyl trimethoxyacetate. Other strategies were unsuccessful.
N-羟基-4-氧代喹唑啉-2-羧酰胺衍生物(环状异羟肟酸)和相关的吡啶基和噻吩基取代的类似物,以及N-羟基次黄嘌呤-2-羧酰胺是首次合成,其方法为四步步骤,涉及氨基异羟肟酸酯与三甲氧基乙酸甲酯的平稳反应。其他策略均未成功。
