A Novel One-Step Conversion of α,β-Epoxy Ketones to o-Dichlorobenzaldehydes by the Vilsmeier Reaction
摘要:
A novel, versatile one-step synthesis of o-dichlorobenzaldehydes has been developed. Acyclic alpha,beta-epoxy ketones undergo the Vilsmeier reaction to afford o-dichlorobenzenemono- and dicarboxaldehydes whereas cyclic alpha,beta-epoxy ketones gave o-dichlorobenzenecarboxaldehydes and chlorobenzenedicarboxaldehydes.

Described herein are spiro and cyclic bis-benzylidine proteasome inhibitors, which inhibit the proteasome function through either ubiquitin receptor ADRM1/RPN13 or proteasome DUB enzymes (USP14, UCH37 and RPN11), and which can be used for the treatment of cancers/diabetes/neurological disorders.
