Ceric(IV) ammonium nitrate in the selective conversion of hydrazides to esters
摘要:
Hydrazides were treated with ceric(IV) ammonium nitrate (CAN) in the presence of the appropriate alcohol as a nucleophile to afford esters in good yields. Reactions took place exclusively at the hydrazino moiety even when other sensitive groups were present in either of the partners. (C) 1999 Elsevier Science Ltd, All rights reserved.

Cyclic nucleotide phosphodiesterases (PDEs) are represented by a large superfamily of enzymes. A series of hydrazone-based inhibitors was synthesized and shown to be novel, potent, and selective against PDE10A. Optimized compounds of this class were efficacious in animal models of schizophrenia and may be useful for the treatment of this disease. (C) 2011 Elsevier Ltd. All rights reserved.
