Paragraph 0094, (2016/02/18)
The present invention relates to various organic reactions including a method for producing heterocyclic compounds using a [3+2] annulation; a method for producing fluorinated heteroaromatic compounds; and a method for alkylating a meta-position of a phen
A synthesis of (-) supinidine and its regioisomer by intramolecular oxime olefin cycloaddition

, p. 2317 - 2324 (2007/10/02)
A synthesis of (-)supinidine 1 and its regioisomer 2 from L-proline is described. The key step is a thermal intramolecular oxime-olefin cycloaddition; dimerization products resulting from intramolecular nitrone formation were also isolated.
DIASTEREOSELECTIVE ALKYLATION OF CHIRAL TIN(II) ENOLATES ONTO CYCLIC ACYL IMINIUM IONS. ASYMMETRIC TOTAL SYNTHESIS OF (-)-SUPINIDINE

, p. 6361 - 6380 (2007/10/02)
The scope and mechanism of the asymmetric alkylation of chiral tin(II) enolate 10 with cyclic acyl iminium ion 5 were investigated.An application of the reaction to the asymmetric synthesis of (-)-supinidine was also achieved.
