A FACILE SYNTHESIS OF ο-SUBSTITUTED CONJUGATED POLYENONES VIA ARSONIUM SALT AND ITS APPLICATION TOWARDS THE SYNTHESIS OF NAVENONE A

Article abstract of DOI:10.1016/S0040-4039(00)96068-4

In the presence of K2CO3, a variety of aldehydes condensed with the arsonium bromide 8 at 0-3 deg C to give exclusively ο-substituted polyenones 1 in good yields, and the synthesis of navenone A was achieved by this procedure.
