Stereochemical reassignment of Mehta and Kundu's spiculoic acid a analogue.

A close examination of Mehta and Kundu's synthesis of an analogue of spiculoic acid A revealed discrepancies between their proposed structure and corresponding data. A revised structure is proposed for Mehta and Kundu's analogue after a careful analysis of their key synthetic transformations and published data. [reaction see text].
