B. V. Subba Reddy,A. Venkateswarlu,Prashant Borkar,J. S. Yadav,Marumudi Kanakaraju,A. C. Kunwar,B. Sridhar +6 more
TL;DR: A novel thia-Prins bicyclization approach has been developed for the first time for the synthesis of hexahydro-2H-thieno[3,2-c]thiopyran derivatives from the coupling of homoallylic mercaptans such as hex-3-ene-1,6-dithiol with various aldehydes using 10 mol % InBr3 in dichloromethane with high selectivity.

Nucleophilic β-Oniovinylation: Concept, Mechanism, Scope, and Applications
TL;DR: A series of Michael systems with donor functions in the beta-position is easily synthesized, which represent a virtually unexplored class of compounds and represent a source for useful further transformations.

Secondary–secondary diamine catalysts for the enantioselective Michael addition of cyclic ketones to nitroalkenes
Sunil V. Pansare,Raie Lene Kirby +1 more
TL;DR: Secondary secondary diamines derived from S-proline are efficient catalysts for the ketone-nitroalkene Michael addition reaction as mentioned in this paper, and the stereoselectivity of the Michael addition is dependant on the pKa of the N-substituted aminomethyl pendant in these diamines.
