The firsttotalsynthesis of neuritogenic gangliosideGAA-7 was achieved using the glucosyl ceramide (Glc-Cer) cassette approach. The stereocenter triad within the ceramide moiety of the target molecule was efficiently established from Dlyxose. The assembly of the ceramide moiety was followed by glycosylation with glucosyl donors to give Glc-Cer cassettes, which underwent conjugation with the oligosaccha
