The Stabilized Iminium Ylide-Olefin Cycloaddition Reaction. Total Synthesis of Sceletium Alkaloid A4

A new method for performing an intramolecular cycloaddition generating two carbon-carbon bonds utilizing a stabilized iminium ylide (3) has been developed.In practice, an olefin aldehyde is condensed with a secondary amino acid ester, generating 3 i

SYNTHESIS OF ALKALOIDS, (+/-)-SCELETIUM ALKALOID A4 AND (+/-)-N-ACETYLTORTUOSAMINE

Synthesis of alkaloids, (+/-)-Sceletium alkaloid A4 and (+/-)-N-acetyltortuosamine, was accomplished by application of a new method for constructing cycloalkenopyridines by thermal rearrangement of oxime O-allyl ethers.
