Anodic cyanation of C-4 hydroxylated piperidines: total synthesis of (±)-alkaloid 241D
摘要:
A stereospecific synthesis of dendrobates (+/-)-alkaloid 241D is described. Key steps in this approach involved the stepwise electrochemical synthesis of C-4 substituted alpha-aminonitriles and their alkylation with iodomethane and 1-bromononane, respectively. The N-aryl group was removed in the last step through a Birch dearomatization followed by the hydrolysis of the intermediate dienamines. (c) 2007 Elsevier Ltd. All rights reserved.
