Synthesis of Carbapyochelins via Diastereoselective Azidation of 5-(Ethoxycarbonyl)methylproline Derivatives
摘要:
Two configurationally stable carbon-based analogues of pyochelin have been prepared from Boc-pyroglutamic acid-tert-butyl ester in 11 and 13 steps. Introduction of the amino group was achieved by a highly diastereoselective electrophilic azidation reaction to afford novel bis-alpha-amino acid proline derivatives.
