6-dimethylpyrrolo[2,3-d]-1,3-oxazin-4-ones were synthesized from 2-amino-3-tert-butoxy-carbonyl-4,5-dimethylpyrroles. Two methods were used, cyclodehydration of 2-acylamino-3-carboxypyrroles with acetic anhydride and direct conversion of the 5,6-dimethylpyrrolo[2,3-d]-1,3-oxazin-2,4-diones to the title compounds with an anhydride directly providing the 2 substituent. Molecular modeling techniques revealed
从2-氨基-3-叔丁基丁氧基羰基-4,5-二甲基吡咯合成了一系列新颖的5,6-二甲基吡咯并[2,3- d ] -1,3-恶嗪-4-酮。使用了两种方法,将2-酰基氨基-3-羧基吡咯与乙酸酐进行环脱水,以及将5,6-二甲基吡咯并[2,3 - d ] -1,3-恶嗪-2,4-二酮直接转化为标题化合物与酸酐直接提供2-取代基。分子建模技术表明,这些吡咯并[2,3- d ]恶嗪酮是烯丙胺抗真菌剂的刚性类似物。测试了这些化合物对毛癣菌和Scopulariopsis sp。的体外活性。
