摘要

Results We chose, as the initial system for investigation, esters of 3-substituted-6-azidohexa- 2, 4-dienoic acids. It appeared these compounds could be made satisfactorily and with good flexibility as to the identity of the 3-substituent, by addition of a protected (3-hydroxy-cis-1- propeny1) copper to 3-substituted propynoate esters. Conversion of propargyl alcohol to the THP-protected (2)-vinyl iodide 2 proceeded via closely precedented4 iodination and ...
