Angewandte Chemie, EarlyView.Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes
Angewandte Chemie, EarlyView.The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

Some sigmatropic rearrangements of polyfluoroaromatic and heteroaromatic compounds [PDF]
, 1986 This Thesis describes some [3,3] and [2,3] -sigmatropic rearrangements that can occur in a variety of polyfluoroaromatic and -heteroaromatic compounds. The presence of fluorine on the aromatic moiety precludes the normal rearomatization process. The

Catalytic Enantioselective Allyl–Allyl Cross-Coupling with a Borylated Allylboronate
, 2016 Catalytic enantioselective allyl–allyl cross-coupling of a borylated allylboronate reagent gives versatile borylated chiral 1,5-hexadienes. These compounds may be manipulated in a number of useful ways to give functionalized chiral building blocks for ...
