Synthesis of isoquinoline and yohimbinoid alkaloids
A systematic survey of the different synthetic methodologies available for the syntheses of isoquinoline and yohimbinoid alkaloids revealed that the general approaches to these compounds involved either an A/B C — D/—i E approach or a D/E — C/B/A approach% We have now devised a novel method for the syntheses of both the isoquinoline and indole alkaloids belonging to the tetra— hydroprotoberberi...
متن کاملPhosphate mediated biomimetic synthesis of tetrahydroisoquinoline alkaloids.
A one-pot synthesis of tetrahydroisoquinoline alkaloids in a phosphate buffer has been achieved, and a reaction mechanism proposed. The utilisation of mild reaction conditions readily afforded a range of isoquinolines, including norcoclaurine.
متن کاملBeta-phenylethylamines and the isoquinoline alkaloids.
This review covers beta-phenylethylamines and isoquinoline alkaloids derived from them, including further products of oxidation. condensation with formaldehyde and rearrangement, some of which do not contain an isoquinoline system, together with naphthylisoquinoline alkaloids, which have a different biogenetic origin. The occurrence of the alkaloids, with the structures of new bases, together w...
متن کاملPresence of isoquinoline alkaloids in molluscan ganglia.
UNLABELLED Tetrahydropapaveroline and reticuline, isoquinoline alkaloids, were purified and identified in the pedal ganglia of the marine mollusk Mytilus edulis. OBJECTIVES To determine the presence of tetrahydropapaveroline and reticuline, isoquinoline alkaloids, in animal tissues previously shown to express opiate receptors. METHODS AND RESULTS This was achieved by high performance liquid...
متن کاملA concise total synthesis of (±)-cipadonoid B from synthetic azedaralide.
The tetranortriterpene cipadonoid B was efficiently constructed from synthetic azedaralide in a one-pot cascade, via the underutilised ketal-Claisen rearrangement.
