A sequential one-pot, two-step, three-component reaction for efficient synthesis of spiro-substituted 1,3-thiazine library has been developed. The syntheses were achieved by reacting cyanoacetamide with isothiocyanate derivatives to give rise to 2-cyano-3-mercaptoacrylamides, which are trapped in situ by various cycloketones through cyclization, providing multifunctionalized spiro-substituted 1,3-thiazine
已经开发出有效合成螺取代的1,3-噻嗪文库的顺序一锅,两步,三组分反应。通过使氰基乙酰胺与异硫氰酸酯衍生物反应以生成2-氰基-3-巯基丙烯酰胺,通过各种环酮通过环化将其原位捕获,从而提供多官能化的螺环取代的1,3-噻嗪类似物,从而实现了合成。该步骤的特点是反应时间短,通常收率高至优异,原料容易获得,操作简便。这种化学方法为1,3-噻嗪骨架的多样性导向构建提供了有效而有前途的合成策略。
