Dibrominative Spirocyclization of 2-Butynolyl Anilides: Synthesis of gem-Dibromospirocyclic Benzo[ d][1,3]oxazines and Their Application in the Synthesis of 4 H-Furo[3,2- b]indoles

The combination of catalytic aqueous hydrochloric acid (HCl) and N-bromosuccinimide (NBS) generated electrophilic bromine monochloride (BrCl), which readily induced spiroannulation of 2-alkynolyl anilides (n = 1-3) to form gem-dibromospirocyclic benzo[d][

Silver-Catalyzed Oxyphosphorylation of Unactivated Alkynes

Here, we describe an application of hydroazidation in the instant activation of alkynes for achieving the oxyphosphorylation of unactivated alkynes with diarylphosphinoyl radicals under mild reaction conditions. This reaction provides a method for accessing β-ketophosphine oxides and phosphorus-containing pyrroles. (Figure presented.).

Synthesis of 2,2,2-Trifluoroethyl Oxazoles, Oxazolines and Furans via Alkyne Oxytrifluoromethylation

This study reports an oxytrifluoromethylation method for construction of oxazoles and furans motif and the concurrent incorporation of a 2,2,2-trifluoroethyl group at the aromatic C5-position. High-valent copper(III) trifluoromethyl compounds are crucial
