An easy access to the optically active Azocine Derivatives
Tetrahedron Letters, 1995Co-Authors: Yasuhiro Torisawa, Yumiko Motohashi, Tohru Hino, Masako NakagawaAbstract:Convenient synthetic routes were devised for the preparation of the optically active Azocine Derivative from the protected serinal (1), which will be useful in manzamine synthetic study.

Uncommon expansion of piperidine ring into hydroAzocine ring in reactions of some piperidine β-acyl Derivatives with acetylenecarboxylic acids esters
'Pleiades Publishing Ltd', 2020Co-Authors: Malkova A.v., Polyanskii K.b., Soldatenkov A.t., Soldatova S.a., Merkulova N.l., Khrustalev V.n.Abstract:Cyclohexanone condensation with formaldehyde and methylamine led to the formation of 4ahydroxy-2-methyloctahydrospiro[isoquinoline-4,1′-cyclohexan]-2′-one whose structure was established by means of X-ray diffraction (XRD) analysis. This spiro compound reacted with acetylenecarboxylic acids esters with unexpected conversion of its piperidine ring into a hexahydroAzocine cycle. The uncommon expansion reaction of the β-acyl-substituted piperidine ring into a hexahydroAzocine cycle is confirmed by the analogous conversion of 4-hydroxy-1-methyl-4-phenylpiperidin-3-yl(phenyl)methanone into Azocine Derivative at treating with methyl propiolate. © 2016 Pleiades Publishing, Ltd
