Synthesis of Anemoclemosides A and B, Two Saponins Isolated from Anemoclema glaucifolium

Steroidal and triterpenoid saponins are attractive for their wide-ranging pharmacological properties. The triterpenoid saponins Anemoclemoside A and B are root constituents of the Chinese folk medicinal plant Anemoclema glaucifolium (Ranunculaceae). Both

The first convergent total synthesis of penarolide sulfate A2, a novel α-glucosidase inhibitor

Penarolide sulfate A2, a 31-membered macrolide encompassing a proline residue and three sulfate groups, was firstly synthesized in 16 linear steps with 4.8% overall yield. Three consecutive stereogenic centers in penarolide sulfate A2 were efficiently derived from natural chiral template l-arabinose. The crucial assembly reactions included Brown asymmetric allylation, olefin cross-metathesis, alkyne-epoxide coupling, and macrolactamization. The anti-yeast α-glucosidase activities of penarolide sulfate A2 and its fully desulfated derivative were examined showing IC50 values of 4.87 and 10.74 μg mL-1, respectively.

Studies on enolization of aldehydo-aldose derivatives

Acetylation of the 2,3-O-isopropylidene derivative (1) of d-glyceraldehyde with hot acetic anhydride in the presence of sodium acetate give a mixture of (Z)- and (E)-enol acetates (2 and 3), together with the acetylated racemic aldehydrol (4) of 1. Likewise, the acyclic aldehydo 2,3:4,5-diisopropylidene acetals of d- and l-arabinose, d-xylose, and d-ribose underwent conversion into enol acetates, with the (Z) isomers preponderating, and convertible photochemically into the corresponding (E) isomers. Under other conditions of acetylation, the aldehydo derivatives were converted into the corresponding aldehydrol diacetates.
