1. TBAB-catalyzed 1,6-conjugate diazotization of para-quinone methides: A very effective access to polysubstituted α-diazocarbonyl compounds

Author

Zhang-Qin Liu, Sheng-Shu Liu, and Xiao-Yu Guan

Subjects
α-Diazocarbonyl compounds, Tetrabutyl ammonium bromide, 1,6-Conjugate diazotization, High atom economy, Chemistry, QD1-999
Abstract

A highly efficient diazotization of diazoacetates with para-quinone methides has been established via a tetrabutyl ammonium bromide (TBAB)-catalyzed 1,6-conjugated addition pathway. This methodology affords a convenient, safe, and rapid way to generating diverse polysubstituted α-diazocarbonyl compounds, displaying good functional group tolerance, high atom economy, and easy accessibility.

Subjects
sulfa-1,6-conjugated addition, unsymmetrical diarylmethyl sulfones, green and sustainable chemistry, synthesis in water, Organic chemistry, QD241-441
Abstract

A highly efficient sulfonylation of para-quinone methides with sulfonyl hydrazines in water has been developed on the basis of the mode involving a tetrabutyl ammonium bromide (TBAB)-promoted sulfa-1,6-conjugated addition pathway. This reaction provides a green and sustainable method to synthesize various unsymmetrical diarylmethyl sulfones, showing good functional group tolerance, scalability, and regioselectivity. Further transformation of the resulting diarylmethyl sulfones provides an efficient route to some functionalized molecules.

Abstract

A novel sulfonylation of para-quinone methides with sodium arylsulfinates has been developed via acetic acid promoted sulfa-Michael addition. This reaction provides an inexpensive and efficient method to synthesize various unsymmetrical diarylmethyl sulfones, displaying the advantages of high atom economy, good functional group tolerance, scalability, and environmentally friendly operation. Derivations of target products are also demonstrated.
