The first totalsyntheses of multifidosidesA–C have been achieved. The synthetic strategy is characterized by catalytic site‐selective acylation of unprotected glycoside precursors in the final stage of the synthesis. High functional‐group tolerance of the site‐selective acylation, promoted by an organocatalyst, enabled the conventionally difficult molecular transformation in a predictable and reliable
