Julia‐Kocienski‐Like Connective C−C and C=C Bond‐Forming Reaction

Abstract In this paper, we present a one‐pot protocol that enables a straightforward and selective transformation of alkyl benzothiazol‐2‐yl and phenyltetrazol‐2‐yl sulfones and acyl chlorides into ketones, E‐olefins, Z‐olefins, and even pyrroles. The final product of the reaction depends on the proper choice of the reaction workup. Notably, the protocol designed for olefin formation allows a switch between E‐ and Z‐olefin formation by the correct choice of the reaction workup. These developed protocols facilitate the formation of all compounds under mild reaction conditions, as evidenced by the synthesis of (nitro)‐fatty acids, and the concept can be extended to other product formations, as demonstrated by the synthesis of pyrroles.
