A series of amides, including α-bromo hydroxamates, N-alkoxyamides, and N-aryloxyamides, were subjected to phosphine-catalyzed ring-opening O-selective addition with cyclopropenones, producing various special α,β-unsaturated esters containing oxime ether motif, in moderate to excellent yields, with high regioselectivity, and exclusive O-selectivity. The methodology is highly atom-economical, with simple
一系列酰胺,包括α-溴异羟肟酸酯、 N-烷氧基酰胺和N-芳氧基酰胺,在膦催化下与环丙烯酮进行开环O-选择性加成,生成各种含有肟醚基序的特殊α,β-不饱和酯,产率中等至优异,具有高区域选择性和独特的O选择性。该方法具有高度原子经济性、操作步骤简单、底物范围广(超过44个例子)。
