Different Lewis acid promotor-steered highly regioselective phosphorylation of tertiary enamides with diverse H-phosphonates or H-phosphine oxides was developed. Under the catalysis of iron salt, the phosphonyl group was introduced into the α-position of tertiary enamides, affording various α-phosphorylated amides in high efficiency. On the other hand, the β-phosphorylated tertiary enamides were efficiently
开发了具有不同 H-膦酸盐或 H-氧化膦的叔烯酰胺的不同路易斯酸促进剂引导的高度区域选择性磷酸化。在铁盐的催化下,将膦酰基引入叔烯酰胺的α位,高效制备各种α-磷酸化酰胺。另一方面,在乙酰丙酮锰(III)的存在下,β-磷酸化叔烯酰胺作为产物有效地获得。
