Reaction of Arynes with Vinyl Sulfoxides: Highly Stereospecific Synthesis of ortho-Sulfinylaryl Vinyl Ethers
Li, Yuanming,Studer, Armido
, p. 666 - 669 (2017/02/10)
The reaction of in situ generated arynes with aryl vinyl sulfoxides provides ortho-arylsulfinylaryl vinyl ethers via aryne σ-bond insertion into the S-O-bond and concomitant stereospecific S-O-vinyl migration. The cascade allows preparing di- or trisubsti

An efficient one-pot, three-component synthesis of vinyl sulfones via iodide-catalyzed radical alkenylation using aryl diazonium salts, terminal alkenes and DABSO is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible radical mechanism.
New carbocyclic nucleosides: Synthesis of carbocyclic pseudoisocytidine and its analogs

Cyclopentane-containing nucleoside analogs with a CC connection between the (heterocyclic) base and the carbocyclic scaffold are quite rare. Herein, we report the synthesis of previously unknown racemic carbocyclic pseudoisocytidine and its analogs, which
The phenylsulfonyl group as a temporal regiochemical controller in the catalytic asymmetric 1,3-dipolar cycloaddition of azomethine ylides

(Chemical Equation Presented) Controlling the regioselectivity: The phenylsulfonyl group controlled the regioselectivity in the title reaction to afford pyrrolidine-2,3-dicarboxylates with good regioselectivity and high exo selectivity and enantioselectivity (see scheme). The products are precursors to substituted pyrrolidines and pyrrolines that are not attainable by direct 1,3-dipolar cycloadditions with typical acrylates.
Regiochemical Control of the Diels-Alder Reactions with β-Phenylsulphonylacrylate Esters
Buss, Antony D.,Hirst, Gavin C.,Parsons, Philip J.
, p. 1836 - 1837 (2007/10/02)
Alkyl α-phenylsulphonylacrylates have been made as geometrically pure isomers; the Z-isomer reacts with dienes in Diels-Alder cycloadditions to afford the oposite regiochemistry to that observed with the E-isomer and this provides a useful method for reversing normal carbonyl directing effects.
