A very mild method of decomposition of various α-diazo carbonyl compounds 1 in the presence of environmentally attractive solid acids such as montmorillonite K-10 or zeolite H-Y in a heterogeneous manner to furnish α-hydroxy/alkoxy ketones in very good yield is reported. Interestingly, novel bicycloalkane-1,3-diones and 3-furanones were obtained as unusual products in the case of aliphatic/alicyclic α-diazo carbonyl compounds.
报告采用一种非常温和的方法,在对环境有吸引力的固体酸(如
蒙脱石 K-10 或
沸石 H-Y)存在下,以异构方式分解各种δ-重氮羰基化合物 1,从而以非常好的收率得到δ-羟基/烷氧基酮。有趣的是,在脂肪族/脂环族 δ-重氮羰基化合物中,作为不常见的产物,获得了新型双环烷-1,3-二酮和 3-
呋喃酮。
