A coupling reaction between sulfonyl radicals and silver-based carbenes has been well established. This simple radical-carbene coupling (RCC) process provided an efficient approach to a variety of β-carbonyl arylsulfones from sodium arylsulfinates and diazo compounds, and was characterized by wide substrate scope, easy scale-up, simple manipulation, accessible starting materials, and mild reaction conditions.

The present invention relates to a method for manufacturing a compound having a sulfonyl group, which includes a step for reacting thiosulfonates in a solvent comprising nucleophilic bases with an electrophilic agent. Accordingly, the present invention can manufacture the compound having the sulfonyl group with a variety of structures with high efficiency and high yield through more simplified processes than conventional methods.COPYRIGHT KIPO 2018
New Diastereoselective Route to 2-Substituted cis-(2S,5S)- and trans-(2S,5R)-5-Alkylpyrrolidines as Indolizidine and Pyrrolizidine Scaffolds

A new and short stereoselective route to the synthesis of enantiopure cis-2,5-disubstituted pyrrolidines as indolizidine or pyrrolizidine scaffolds has been developed. The method, which uses (S)-pyroglutamic acid as a chiral starting material, is based on the ring opening of N-protected 7-lactams by alkyl phenyl sulfone carbanions, followed by desulfonylation and reductive amination of alkyl 7-amino ketones. The diastereoselectivity depends on the substitution of the starting γ-lactams, and on the alkyl group of the phenyl sulfone. Total cis diastereoselectivity was observed in the formation of tert-butyl 5-alkylprolinates. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
