Abstract
The present invention provides an innovative method based on reaction cum separation on single plate concept for efficient evaluation of porphyrins, calix(4)pyrroles and allied macrocycles by in-situ synthesis from pyrrole with aromatic aldehydes and ketones over zeolite based molecular sieve catalysts as sorbents in thin layer chromatography (TLC) using microwave heating. This glass backed zeolite coated TLC plate acts as a micro reactor as well as separator for the in-situ synthesis and chromatographic separation of macrocycles. The process is simple, economical, rapid, selective and finds a possible application in high throughput parallel synthesis and screening on a single micro plate employing microwave irradiation.
