## Abstract Methyl 4‐__O__‐benzyl‐3‐__O__‐methyl‐2‐__O__‐pivaloyl‐α‐L‐rhamnopyranoside (6) was prepared from L‐rhamnose in an improved synthesis in six steps (overall yield: 51%) and was used as the key building block. Acetolysis of 6 gave the glycosyl donor, 1,4‐di‐__O__‐acetyl‐3‐__O__‐methyl‐2‐__
