摘要:

β-(1-Hydroxybut-3-enyl)indoles, which are prepared in high yields from indole-3-carbonyl compounds, could be converted into 1-(β-indolyl)1,3-butadienes, yuehchukene and derivatives, and murrapanine in one step under various acid-catalyzed reaction conditions in THF. As the reactions of β-(1-hydroxypropenyl)indole1 3with alcohol4and8agave exclusively bisnoryuehchukene7cand trinoryuehchukene7d, respectively, our present work also gives strong evidence to support the asssumption that reactions of this type indeed proceed from a Diels-Alder pathway.

摘要:

Two novel triterpenoid saponins named asterbatanoside F (1) and G (2) were isolated from the roots ofAster batangensisand their structures elucidated as 3-O-β-D-glucopyranosyl-23-O-acetyl-bayogenin-28-O-β-D- glucopyranosyl-(1 → 6) - [α-L-rhamnopyranosyl-(1→2)] β-D-glucopyranoside and 3-O-β-D-glucopyranosyl-bayogenin-28-O-β-D-glucopyranosyl-(1→6)-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside by means of spectral data especially 2D NMR including COSY, HETCOR, COLOC, HOHAHA, ROESY and selective INEPT techniques and chemical evidence.
