A Stereoselective Synthesis of Indole-β-N-glycosides: An Application to the Synthesis of Rebeccamycin

Gallant, Michel,Link, James T.,Danishefsky, Samuel J.

, p. 343 - 349 (2007/10/02)

Sodium salts of indoles have been found to open α-1,2-anhydrosugars with inversion yielding indole-β-N-glycosides.This methodology constitutes a concise route from glycals to the biologically active indole-N-glycosides.An application to the total synthesis of rebeccamycin is descibed.
