- Efficient and benign one-pot conversion of n-tosyl-1,4,5,6- tetrahydropyrimidines to pyrimidines via tandem β-elimination and aromatization
-
An efficient, mild, benign, and practical method for one-pot conversion of N-tosyl-1,4,5,6-tetrahydropyrimidines into pyrimidines is discussed in detail. In this method, N-tosyl-1,4,5,6-tetrahydropyrimidines are first prepared via N-tosylation of tetrahyd

- Scope of the suzuki-Miyaura cross-coupling reactions of potassium heteroaryltrifluoroborates
-
A wide variety of bench-stable potassium heteroaryltrifluoroborates were prepared, and general reaction conditions were developed for their cross-coupling to aryl and heteroaryl halides. The cross-coupled products were obtained in good to excellent yields. This method represents an efficient and facile installation of heterocyclic building blocks onto preexisting organic substructures.

- Copper(I)-promoted palladium-catalyzed cross-coupling of unsaturated tri-n-butylstannane with heteroaromatic thioether
-
(Matrix presented) Palladium-catalyzed cross-coupling of vinyl- and arylstannanes with π-electron-deficient heteroaromatics was performed in good yields. This Stille-type reaction was carried out with a methylthioether function as an electrophile in the presence of a copper(I) bromide-dimethyl sulfide complex.
