quinolone-annulated 1,4-thiazine-3-one derivatives has been achieved by using sodium sulfide as the sulfur source and ferric chloride as catalyst in a ligand-free condition. The synthetic procedure is simple, inexpensive, and affords the products in good yields. This methodology is also applicable to naphthalene and benzene systems.
通过在无配体条件下使用硫化钠作为硫源和氯化铁作为催化剂,已经获得了合成香豆素-,喹诺酮-环化的1,4-噻嗪-3-one衍生物的简便方法。合成过程简单,廉价,并以高收率提供产物。该方法学也适用于萘和苯体系。
