Synthesis of oxa-B-ring analogs of colchicine through Rh-catalyzed intramolecular [5+2] cycloaddition

A synthetic approach towards (5R)-5-methyl-6-oxa-desacetamido colchicine as a conformationally defined non-natural colchicine analog with a modified B-ring was undertaken. The synthetic strategy was based on a Rh-catalyzed cascade reaction involving a [5+
