Unexpected N-glycosidation reaction of glycals with 1-amino-anthracene: structure revision and application to the synthesis of new analogues of marmycin A

Org Biomol Chem. 2013 Feb 28;11(8):1383-9. doi: 10.1039/c2ob27020j.

Abstract

An unexpected N-glycosidation reaction of anthracen-1-amine with glycals was identified, and its use in the synthesis of C1' N-linked analogues of natural product marmycin A was explored. The structures of all these products were determined by 1D and 2D NMR, CD spectra, and X-ray crystal analysis. These products were then subjected to Friedel-Crafts acylation, Dess-Martin oxidation and nucleophilic addition leading to novel natural product analogues bearing a quaternary carbon center.
