Cohen A, Siddaraju Y, Marek I
Org Lett . 2022 Nov; 24(45):8322-8325. PMID: 36354275
We report the directed diastereoselective Simmons-Smith cyclopropanation and vanadium-catalyzed epoxidation reactions of alkenyl cyclopropyl carbinol derivatives. The reaction furnished densely substituted stereodefined bicyclopropanes and cyclopropyl oxiranes as a single diastereomer...

Siddaraju Y, Sabbatani J, Cohen A, Marek I
Angew Chem Int Ed Engl . 2022 May; 61(28):e202203652. PMID: 35521738
The diastereoselective double carbometalation reaction of cyclopropenes provides, in a single-pot operation, two ω-ene-[1,1]-bicyclopropyl ester derivatives. One regioisomer then undergoes a Pd-catalyzed addition of aryl iodide to provide skipped dienes...

Siddaraju Y, Prabhu K
ACS Omega . 2019 Aug; 3(5):4908-4917. PMID: 31458707
Metal-free chemoselective hydroamination of styrene derivatives has been achieved with high chemoselectivity over sulfenylation of 1-tetrazole-5-thiol using a catalytic amount of iodine. The scope of this methodology has been extended...

Siddaraju Y, Prabhu K
J Org Chem . 2018 Jul; 83(18):11145-11153. PMID: 30032620
A chemoselective formation of C-N bond catalyzed by iodine has been developed using heterocyclic thiols and thiones. The reaction occurs at the nitrogen center over the sulfur, leading to the...

Siddaraju Y, Prabhu K
J Org Chem . 2018 Feb; 83(5):2986-2992. PMID: 29389131
A rare regioselective sulfenylation of α'-CH or α'-CH bonds adjacent to α,β-unsaturated ketones using dimethyl sulfoxide as an oxidant and a substoichiometric amount of aq HI as an additive is...

Siddaraju Y, Prabhu K
Org Biomol Chem . 2017 Jun; 15(24):5191-5196. PMID: 28590497
An iodine catalyzed sulfenylation of pyrazolones with a diverse range of heterocyclic thiols, heterocyclic thiones and disulfides has been described using dimethyl sulfoxide as an oxidant, which is an inexpensive,...

Siddaraju Y, Prabhu K
J Org Chem . 2017 Feb; 82(6):3084-3093. PMID: 28229592
Synthesis of polyfunctionalized aminothioalkenes has been demonstrated using iodine as a catalyst (30 mol %) and dimethyl sulfoxide as an oxidant under metal-free reaction conditions. This methodology allows a facile...

Siddaraju Y, Prabhu K
Org Lett . 2016 Dec; 18(23):6090-6093. PMID: 27934388
A metal-free regioselective sulfenylation of the α-CH group of ketones has been achieved in the presence of the α-CH or α-CH group using the cross dehydrogenative (CDC) strategy. Aldehydes also...
