and 2-hydroxy-2-methylchromene under transition metal-free conditions. This strategy proceeds through double Michael addition and oxygen-migration, thus providing a straight way for the synthesis of chromone derivatives.
我们开发了邻卤芳基炔酮和 2-羟基-2-甲基色烯在无过渡
金属条件下的级联反应。该策略通过双迈克尔加成和氧迁移进行,从而为
色酮衍
生物的合成提供了一条直接的途径。
