Heck reactions of amino acid building blocks: application to the synthesis of pyrrololine analogues
摘要:
Heck reactions of unsaturated amino acid building blocks are described which allow acess to homo- and bis-homophenylalanine derivatives and to gamma,delta-unsaturated amino acids. Preliminary synthetic studies utilising this chemistry for the preparation of pyrrololine and deoxypyrrololine analogues are also reported. (C) 2002 Elsevier Science Ltd. All rights reserved.

compound 25 undergo hydroboration with 9-BBN-H followed by palladium-catalyzedSuzukicoupling reactions with aryl and vinyl halides. After one-pot hydrolysis-oxidation, a range of known and novel nonproteinogenic amino acids were isolated as their N-protected derivatives. These novel organoborane homoalanine anion equivalents are generated and transformed under mild conditions and with wide functional
