Abstract

A synthesis of the proposed structure of cryptoconcatone H and one diastereoisomer has been achieved, featuring a tandem deprotection–oxa-Michael addition to establish the tetrahydropyran moiety. Comparison of the NMR spectroscopic data confirms that the original structural assignment was incorrect.
