A simple and green one pot protocol for the synthesis of bioactive pyran annulated heterocyclic
compounds at room temperature in ethanol has been developed using lemon peel powder as a
catalyst. This method provides operational simplicity and environmentally benign green approach.
All the synthesized compounds were evaluated for antimicrobial activity against
E. coli
,
Welsiella
sp
.
and
fusarium moniliforme
.
