Enamides and dienamides in phosphoric acid-catalysed enantioselective cycloadditions for the synthesis of chiral amines

This feature article describes how enamides and dienamides can participate in chiral phosphoric acid catalyzed enantioselective cycloadditions to prepare a wide range of cyclic amines.

A new triterpene hexaglycoside from the bark of Kalopanax septemlobus (Thunb.) Koidz

The new triterpene glycoside 3-O-β-D-xylopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosylhederagenin 28-O-β-D-gluco-pyranosyl-(1→6)-β-D-glucopyranoside, named septemoside A (1), and the known 3-O-α-L-rhamnopyranosyl-(1→2)-O-α-L-arabinopyranoside-28-O-β-D-glucopyran-osyl-(1→6)-O-β-D-glucopyranosyl ester of hederagenin (2), were isolated from the bark of Kalopanax septemlobus. The structure elucidation of the compounds was based on spectroscopic evidence, including HRESIMS, 1D and 2D-NMR analysis.
