Synthesis of the Carboline Disaccharide Domain of Shishijimicin A
摘要:
A synthetic route to the carboline disaccharide domain (2) of shishljlmicin A (1) has been developed. The convergent synthesis relies on a novel application of the Reetz-Muller-Starke reaction to form the central, sulfur-bearing quaternary carbon center and addition of the carboline structural motif as a dianion to a disaccharide aldehyde fragment.
