Abstract
AbstractMatijin‐Su (1) is a phenylalanine dipeptide compound with anti‐hepatitis B virus (HBV) activity. Previous reports suggest that the synthesis of glycosylated Matijin‐Su derivatives needs at least 10 steps. To simplify the synthetic procedure, we have developed a shorter and more efficient method for the preparation via ultrasound irradiation. Two galactopyranosylated (2) and two glucopyranosylated (3) derivatives were synthesized in 6 or 7 steps. The overall yields for the total synthesis of galactopyranosylated derivatives were markedly increased to 39% (2a) or 22% (2b). And the yields for glucopyranosylated derivatives also reached 29% (3a) or 16% (3b).
