Journal ArticleDOI
Catalyst-controlled divergence in cycloisomerisation reactions of N-propargyl-N-vinyl sulfonamides: gold-catalysed synthesis of 2-sulfonylmethyl pyrroles and dihydropyridines.
Sridhar Undeela,Srinivas Thadkapally,Jagadeesh Babu Nanubolu,Kiran Kumar Singarapu,Rajeev S. Menon +4 more
TL;DR: Gold-catalysed, divergent synthesis of 2-sulfonylmethyl pyrroles and dihydropyridines from N-propargyl-N-vinyl sulfonamides has been achieved.
Journal ArticleDOI
Regioselective synthesis of substituted arenes via aerobic oxidative [3 + 3] benzannulation reactions of α,β-unsaturated aldehydes and ketones.
Prabhakar Ramchandra Joshi,Sridhar Undeela,Doni Dhanoj Reddy,Kiran Kumar Singarapu,Rajeev S. Menon +4 more
TL;DR: This open-flask, metal-free reaction does not require anhydrous solvents, proceeds under mild conditions, and uses atmospheric oxygen as the oxidant to afford high yields of the 3-(arylsulfonyl)benzoic acid esters.
Journal ArticleDOI
The facile synthesis of 1-benzoazepine derivatives via gold-catalyzed regioselective cycloisomerization reactions of N-(o-alkynylaryl)-N-vinyl sulfonamides.
Sridhar Undeela,Gurram Ravikumar,Jagadeesh Babu Nanubolu,Kiran Kumar Singarapu,Rajeev S. Menon,Rajeev S. Menon +5 more
TL;DR: Gold-catalyzed, regioselective cycloisomerization of N-(o-alkynylaryl)-N-vinyl sulfonamides afforded high yields of 2-sulfonylmethyl-1-benzoazepine derivatives, and this 7-endo-dig selective cyclization proceeds via the incorporation of an exocyclic double bond by a labile 1-benzepine intermediate.
Journal ArticleDOI
A sequential synthesis of substituted furans from aryl alkynes and ketones involving a cerium(IV) ammonium nitrate (CAN)-mediated oxidative cyclization
TL;DR: In this paper, a two-step synthesis of substituted furans from readily available aryl alkynes and ketones is reported, mediated by the combination of cerium(IV) ammonium nitrate and potassium bromide and can be carried out in an open flask.
Journal ArticleDOI
Gold-catalysed regioselective cascade cycloisomerisation reactions of aza-enediynes for the synthesis of substituted benzoisoquinoline derivatives
TL;DR: Aza-enediynes underwent a facile, regioselective gold-catalysed cascade cycloisomerisation to furnish dihydrobenzo[f]isoquinoline derivatives in excellent yields.
