Ride the (micro)wave: The title strategy has been developed for the synthesis of various symmetric or unsymmetric hydroxylated stilbenoids utilizing 4‐halophenols and acrylic acid as coupling partners (see scheme; DMA=N,N‐dimethylacetamide, MW=microwave). Protecting groups are not necessary and a single palladium catalyst is used.
乘(微波):已开发出标题策略,用于使用4-卤代苯酚和丙烯酸作为偶联伙伴来合成各种对称或不对称的羟基二苯乙烯类化合物(参见方案; DMA = N,N-二甲基乙酰胺,MW =微波)。保护基不是必需的,并且使用单一的钯催化剂。
