A novel iodine-promoted difunctionalization of α-C sites in enaminones was demonstrated as a means synthesizing variety fully substituted thiazoles by constructing C–C(CO), C–S, and C–N bonds. This transformation allows the realization unusual aryl C2 synthons simultaneously thioylation dicarbonylation sites. preliminary mechanistic study performed indicated that cleavage C═C bonds involves bicyclization/ring-opening oxidative coupling sequence.

By employing enaminones and thiuram disulfides as starting materials, the frontiers of Newman–Kwart rearrangement have been expanded to alkenyl system for first time. In addition, instead leading formation simple carbamothioates, has led unprecedented construction S-heteroaryls. Depending on differences in enaminone structure, efficient synthesis functionalized isothiazoles thiophenes achieved.

Abstract With an in situ C−H iodination tactic, a method for the synthesis of chromone‐3‐phosphonates was developed with trialkyl/triaryl phosphites as reaction partners o ‐hydroxyphenyl enaminones by palladium catalysis. The product formation consists cascade iodination, chromone annulation, and Arbuzov‐type C−P cross coupling major transformations. In addition to providing enaminone‐based synthetic chromone‐3‐phosphonates, work shows advantage step economy skipping separate operation preparing iodo‐functionalized intermediate.
