Abstract

Since its first appearance,'PCC (pyridinium chlorochromate) has received much attention by synthetic chemists, because of its exceptional versatility as oxidizing agent in many usual and unusual situations. 2 So far no attempts have been made to oxidize methylene groups with PCC. On the other hand, allylic oxidation (Se02, 3 CrO,, and derivatives4) or ether oxidation (Ru04 and Cr036) are well-known. Of course, in more sensitive substrates, like ...
