ABSTRACT
A novel synthesis of N-fused imino-1,2,4-thiadiazolo derivatives is described. This approach involves the inexpensive, nontoxic, recoverable, and easy to handle montmorillonite K10 that catalyzes the coupling of 3-aminoisoquinolines and phenylisothiocyanates to afford the N-fused imino-1,2,4-thiadiazolo isoquinoline motifs in exemplary yields. The main attractions of this synthetic strategy were simple procedure and excellent yields.
