Sulfur ylides first disclosed in 1930 started to gain more attention in the 1960s, thanks mainly
to the studies by Corey and Chaykovsky on their use for the preparation of strained rings …

Sulfoxonium ylides are important surrogates for diazo compounds, and their use in industry
as safer alternatives has been evaluated during recent years. Beyond the known classical …

We report a new procedure for the preparation of NH-sulfoximines from sulfides using PIDA
as an oxidant and ammonium carbamate as the ammonia source. Excellent yields were …

This review describes advances in the literature since 2000 in the area of reactions of
vinylsulfonium and vinylsulfoxonium salts, with a particular emphasis on stereoselective …

Ketenes are mostly used as the remarkable and common starting materials for structurally
diverse five-membered and fused five-membered compounds, such as lactones, furans …

A protocol for the copper-catalyzed N-methylation of sulfoximines with di-tert-butyl peroxide
(DTBP) was developed. This protocol has good functional group tolerance leading to N …

Previously described approaches for the alkylation of NH-sulfoximines typically rely either
on transition metal catalysis, or the use of traditional alkylation reagents and strong bases …

Recent advances in ketene chemistry are reviewed, including synthetic, mechanistic, and
computational studies. Topics include ketene structure determination by experimental and …

The asymmetric synthesis of endocyclic methionine sulfilimines and sulfoximines from
methionine derivatives was explored. The cyclization was performed by using phenyliodine …

Studies of the reaction of lithium enediolates with α, β-unsaturated sulfoxonium salts are
described. γ-Lactones were formed in very good to excellent yields (82%→ 99% for 11 …
