Gold-catalyzed redox cycloisomerization/nucleophilic addition/reduction: direct access to 2-phosphoryl indolin-3-ones

Abstract

An efficient gold(I)-catalyzed redox cycloisomerization/nucleophilic addition/reduction reaction of o-nitroalkynes with various H-phosphorus oxides is established. Through the intramolecular redox cyclization of o-nitroalkynes and subsequent intermolecular nucleophilic addition/reduction with no external...

Visible-Light-Induced Carbene Insertion into P–H Bonds between Acylsilanes and H-Phosphorus Oxides

“…To the best of our knowledge, the light-derived P–H insertion for C–P bond formation has not been explored. In continuation of our research on various carbene reactions for C–P bond formation, , we herein report a visible-light-induced P–H insertion of α-siloxycarbenes between acylsilanes and H -phosphorus oxides (Scheme c), which provides a metal-free and efficient approach for the construction of a C–P bond and creation of α-hydroxyphosphorus oxides.…”

KI-Catalyzed C(sp3)–H Amination and Acyloxylation of Indolin-3-ones Using Air as the Oxidant

“…Due to the high synthetic and biological importance of C2-substituted indolin-3-ones, the development of general methods for the synthesis of C2-substituted indolin-3-ones has attracted the attention of synthetic chemists . Recently, much effort has been made toward direct C­(sp 3 )–H functionalization at the C2 positions of nucleophilic indolin-3-ones .…”
