Metal-free synthesis of activated ynesulfonamides and tertiary enesulfonamides
Andna, Lucile,Miesch, Laurence
, p. 5688 - 5692 (2019/06/19)
An operationally simple synthesis of activated ynesulfonamides and enesulfonamides is described. Ynesulfonamides can be obtained through reaction of sulfonylamides with activated bromoalkynes and Triton B in a short time at room temperature. Likewise, terminal alkynes react with sulfonylamides to provide enesulfonamides. Z/E enesulfonamides can be transformed exclusively into E enesulfonamides.
Copper-catalyzed cross-coupling of vinylsiloxanes with bromoalkynes: Synthesis of enynes

Enynes are versatile building blocks in organic synthesis. A copper-catalyzed Hiyama-type cross-coupling of vinylsiloxanes with bromoalkynes is presented. This mild and efficient method led to the formation of various sensitive enynes. The use of cis, trans, and 1,1′-disubstituted vinylsiloxanes was allowed, and full retention of stereochemistry was observed. Sensitive groups such as halides, unsaturated ketones, and aldehydes were fully tolerated.

The reaction of thiourea with 1-acyl-2-bromoacetylenes in AcOH in the presence of BF3 · Et2O affords 2-amino-4-phenyl(2-thienyl)-1,3-thiazine-6-thiones in high yields.
