Multicomponent Reactions Based on SO₂ Surrogates: Recent Advances

European Journal of Organic Chemistry, Год журнала: 2023, Номер 26(25)

Опубликована: Апрель 25, 2023

Abstract Compounds containing sulfonyl‐derived functional groups have received intensive attention owing to their widespread applications in life science, pharmaceuticals and materials science. To access this type of compounds, the multi‐component sulfonylation reactions relying on sulfur dioxide (SO 2 ) insertion strategy emerged as novel attractive approaches past decade. The utilization SO surrogates for multicomponent (MCRs) improved reaction flexibility step economy. Moreover, some advances been achieved challenging but practical asymmetric MCRs construction high value‐added chiral sulfones. This review aims summarize progress made involving from 2019 2022, point out potentials challenges field.
