Diastereoselective quaternization of ortho-sulfinylbenzyl-methylpropargylic carbanions has been carried out with various allylic, propargylic, and benzylic halides. The stereoselectivity is efficiently controlled by the sulfinyl group, acting as a re

An asymmetric organocatalytic [3 + 3] annulation strategy based on a Michael addition/intramolecular Julia-Kocienski olefination sequence has been developed for the synthesis of 4-substituted-5-nitrocyclohex-1-ene compounds. The strategy is an altern

The reaction of metal alkoxides with β-substituted 2-(p-tolylsulfonyl)acetylenes, involving an anti-Michael addition reaction followed by the in situ elimination of the sulfonyl moiety, provides a direct method for the synthesis of alkyl alkynyl eth

Reactions of α-[2-(p-tolylsulfinyl)phenyl] α-methylidene carbonyl compounds 1 and 2 with alkyl radicals generated from Et3B/O2 and RI give, after protonation, β-alkyl derivatives with a high degree of control of the configuration at the α carbon.

Raney-Ni/EtOH reduction of different N-sulfonylimines provides a new entry for synthesizing sulfonamides in good yields under mild conditions. This protocol, which does not require additional hydrogen, constitutes a cheap, safe, and easy-to-handle al

In this work, we report the use of the asymmetric intramolecular Pauson-Khand reactions of 4-aryl-4-cyano-1,6-enynes for obtaining enantiomerically enriched bicyclo[3.3.0]octenones, and the influence of both the quaternary stereocenter and the sulfur

Allenes are important compounds that exhibit axial chirality and are present in a large number of medicinal and natural products. One of the most frequently used methods for obtaining racemic allenes involves the isomerization of propargylic centers.

The first organocatalytic enantioselective 1,3-dipolar reaction between nitrones and alkynals catalyzed by (S)-2-(fluorodiphenylmethyl)pyrrolidine to give 4-isoxazolines (2,3-dihydroisoxazoles) with high enantiomeric excess, excellent yields and low

We describe the unexpected behavior of the arylsulfonylacetylenes, which suffer an "anti-Michael" addition of organolithiums producing their alkynylation under very mild conditions. The broad scope, excellent yields, and simplicity of the experimenta
