18.6.6.1.2.4 Method 4: Palladium-Catalyzed Reaction of 2-Vinylthiiranes with Isocyanates

DOI: 10.1055/sos-SD-018-00578

Rossi, L., Science of Synthesis, (2005) 18, 627.

The palladium-catalyzed ring expansion of 2-vinylthiiranes with isocyanates affords thiazolidin-2-ones, e.g. ‌339‌, in moderate yields (‌Scheme 243‌). The reaction is catalyzed by a tris(dibenzylideneacetone)dipalladium–chloroform complex in the presence of a bidentate phosphine ligand.[‌558‌]
