  The branched-chain oligosaccharides, 6-O-(β-d-glucopyranosyl)-4-O-(α-l-rhamnopyranosyl)-d-glucopyranose, and 2,6-di-O-β-d-glucopyranosyl)-4-O-(α-l-rhamnopyranosyl)-d-glucopyranose, which compose sarsasaponins, as well as the structurally related 2-O-(β-d-glucopyranosyl)-4-O-(α-l-rhamnopyranosyl)-d-glucopyranose were synthesized stepwise via dehydrative glycosylation by a ternary mixture of p-nitrobenzenesulfonyl chloride, silver triflate, and triethylamine.

  2,6-Di-O-(β-d-glucopyranosyl)-4-O-(α-l-rhamnopyranosyl)-d-glucopyranose was synthesized through three successive glycosylations with the benzyl-protected glycoses starting from the glycosyl acceptor, benzyl 4-O-allyl-6-O-benzoyl-3-O-benzyl-α-d-glucopyranoside.

  2,6-二-O-(β-d-吡喃葡萄糖基)-4-O-(α-l-吡喃鼠李糖基)-d-吡喃葡萄糖是通过从糖基受体苄基开始的三个连续糖基化合成的，其中苄基保护的糖基4-O-烯丙基-6-O-苯甲酰基-3-O-苄基-α-d-吡喃葡萄糖苷。
