Aliphatic and aromatic epoxides react regio- and stereoselectively with indoles and pyrroles in 2,2,2-trifluoroethanol without the use of a catalyst or any other additive. While aromatic epoxides are selectively attacked at the benzylic position, aliphatic epoxides react at the less-substituted position. Chiral epoxides react with >99 % ee (ee=enantiomeric excess).

The present invention provides compounds, specifically thienopyrimidine derivatives, useful as inhibitors of Acetyl CoA Carboxylase (ACC), pharmaceutical compositions thereof, and methods of using the same for treating ACC-mediated disorders such as obesity, dyslipidemia, hyperiipidemia, fungal, parasitic or bacterial infections in a subject. The invention further provides a method of inhibiting ACC in a plant comprising contacting the plant with the inhibitor compound.
Arylazo sulfones were used as Photoacid Generators (PAGs) for the visible-light photorelease of strong sulfonic acids to promote the ringopening of epoxides in benign media (DMC/water mixtures) or under neat conditions. Water, alcohols, azide and thiocyanate anions, as well as electron-rich aromatics were used in the role of the nucleophile. The resulting 1,2-disubstituted adducts were formed mostly
