Abstract
A novel one-pot synthesis of sydnones appended to coumarins (4a–r) via thiazole in presence of silica sulfuric acid as a heterogeneous catalyst is discussed. The use of low cost and reusable silica sulfuric acid as catalyst makes this process feasible and convenient. Further, the title compounds were screened for their α-amylase inhibition (antidiabetic) as well as DNA cleavage activities.
