Pyridine ketone
WebABSTRACT Pyridinium 1,4-zwitterionic thiolates were applied to a formal [3+2]annulation reaction with modified activated alkynes,affording various tetrasubstituted thiophenes with aryl,alkenyl,alkyl or silyl group at the special position.The structural modification of alkyne substrates enabled the synthesis of diverse thiophenes to be achieved using the … WebPyridinium chlorochromate ( PCC) is a milder version of chromic acid. PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. In contrast to …
