Synthesis of diverse azolo[c]quinazolines by palladium(II)- catalyzed aerobic oxidative insertion of isocyanides
We report the palladium(II)-catalyzed aerobic oxidative coupling of isocyanides with various (2-aminophenyl)azoles using air as the stoichiometric oxidant. A diverse range of medicinally valuable azolo[c]quinazolines was obtained by this new approach.

A CONVENIENT SYNTHESIS OF 3,5-DISUBSTITUED-1,2,4-TRIAZOLES
The condensation of an acyl hydrazide and an amidine to afford an acylamidrazone, followed by thermal cyclization, provides a convenient method for preparing 3,5-disubstitued-1,2,4-triazoles in high yields.
