An efficient synthesis of the cuanzine precursor 4d has been achieved beginning with 8-methoxy-dihydro-β-carboline 3b and utilizing as the key step the stereocontrolled alkylation of 16a (and/or 20a) followed by Hg(II)-induced heterocyclization. The structure and stereochemistry of 4d are thereby corroborated by chemical correlation with natural cuanzine 1a.

Abstract
An efficient synthesis of the cuanzine precursor 4d has been achieved beginning with 8-methoxy-dihydro-β-carboline 3b and utilizing as the key step the stereocontrolled alkylation of 16a (and/or 20a) followed by Hg(II)-induced heterocyclization. The structure and stereochemistry of 4d are thereby corroborated by chemical correlation with natural cuanzine 1a.File in questo prodotto:
