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 …

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 …

Selective C–H activation is an area of growing importance in modern organic chemistry.
Herein, we report our efforts in combining organocatalysis and photocatalysis for the …

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 general protocol for the construction of novel densely functionalized γ-lactones was
developed in good to excellent yields with high diastereoselectivity from easily available N …

Stabilised sulfur ylides are synthetically appealing compounds, which reactivity under
Brønsted acid catalysis has been poorly explored. Herein, we report a new catalyst‐and …

The article focuses on a study conducted on the flow synthesis of substituted gamma-
lactones through consecutive photocatalytic and reductive reactions. Flow reactors are used …

A novel approach to synthesize hydroxy lactones using flow chemistry is reported. The
system could be applied to a variety of functionalized alkenoic acids allowing the simple and …

α, β-Unsaturated carbonyl compounds are significant moieties in many biological molecules
and have attracted considerable attention in organic synthetic chemistry. A Pd-catalyzed …

A method for the enantioselective synthesis of γ-lactones through the reaction of
enantioenriched sulfoxonium ylides, aldehydes, and ketenes was developed …
