I2/TBHP-mediated reaction of sulfonylhydrazides with alkynes: synthesis of (E)-β-iodovinyl sulfones
摘要:
An efficient and simple procedure for the syntheses of (E)-beta-iodovinyl sulfones through TBHP mediated reaction of sulfonylhydrazides and iodine with aryl acetylenes has been developed. This method offers several advantages such as high atom economy, environmentally benign oxidant, less byproduct, and easy operation. (C) 2013 Elsevier Ltd. All rights reserved.
A novel protocol for synthesis of (E)-β-Iodovinyl sulfones via NaI-mediated of aryl sulfonyl chloride with alkynes is described, featuring transition-metal-free condition, commercial available substrates, convenient operation, as well as good functional group compatibility. A wide variety of substrate application and good functional group tolerance is provided by this approach, giving multiple (E)-β-Iodovinyl
