Significance
The first synthesis of the natural (-)-antipode of Virantmycin is reported. Virantmycin is a potent inhibitor of RNA and DNA viruses. It is isolated from Streptomyces nitrosporeus. The related benzstatins inhibit glutamate toxicity and lipid peroxidation.
Comment
The difficult stereoselective construction of a chiral quaternary center was accomplished by a stereospecific rearrangement of an α,α-disubstituted indoline-2-methanol B via aziridinium ion C.
