Photoredox Catalytic Phosphite-Mediated Deoxygenation of α-Diketones Enables Wolff Rearrangement and Staudinger Synthesis of β-Lactams

A novel visible-light-driven catalytic activation of C=O bonds by exploiting the photoredox chemistry of 1,3,2-dioxaphospholes, readily accessible from α-diketones and trialkyl phosphites, is reported. This mild and environmentally friendly strategy provides an unprecedented and efficient access to the Wolff rearrangement reaction which traditionally entails α-diazoketones as precursors. The resulting ketenes could be precisely trapped by alcohols/thiols to give α-aryl (thio)acetates and by imines to afford the valuable β-lactams in up to 99 % yields.

Syntheses of 1-(Diphenylacetyl)-3,3,4,4-tetraphenyl-2-azetidinone and 1-Benzyl-3,3,4-triphenyl-2-azetidinone

Thermal decomposition of azebenzil (I) with 1,1-diphenylmethyleneimine (II) (in 2:1 molar ratio) yields a mixture of 1-(diphenylacetyl)-3,3,4,4-tetraphenyl-2-azetidinone (III) and N-(α-methoxydiphenylmethyl)diphenylacetamide (IV).The products, III and IV,
