Solvent-free synthesis of 1-(hydroxyquinolyl)- and 1-(hydroxyisoquinolyl)- 1,2,3,4-tetrahydroisoquinolines by modified mannich reaction

The solvent-free synthesis of 1-(hydroxyquinolyl)- and 1- (hydroxyisoquinolyl)-1,2,3,4-tetrahydroisoquinoline derivatives is reported. The tested reaction conditions involved classical heating at 80-100 C and microwave agitation at the same temperature. Both reaction conditions yielded the compounds in good yield (57-92%), but the use of microwave conditions allowed the reaction time to be decreased. Georg Thieme Verlag Stuttgart New York.

HALO DERIVATIVES OF 8-AZA-D-HOMOGONANES

A simple one-stage method was developed for synthesizing 15,17-dihalo and 17-halo derivatives of 16,16-dimethyl-8-aza-D-homogona-1,3,5(10),13-tetraene-12,17a-diones.The reaction proceeds regio- and stereoselectively, yielding 17-halo derivatives of 8-aza-D-homogonanes from 4-halo-2-acetyldimedones and 15,17-dichloro derivative from 4,6-dichloro-2-acetyldimedone.The 17-halo derivatives exist in solutions as a mixture of cis and trans isomers at C17 with respect to C9H as a result of keto-enol equilibrium at C17a.In the crystalline state only the trans isomer occurs.In the presence of acids an enolimmonium derivatives with trans arrangement of the halogen at C17 and C9H is formed, which exists only in solution.We isolated, together with the 15,17-dihalo derivative, a mino product, which was assigned the structure of cyclopropano<2',3':15,16>-8-azogonane on the basis of physicochemical data.

Asymmetric Synthesis of Isoquinoline Alkaloids: 2004-2015

In the past decade, the asymmetric synthesis of chiral nonracemic isoquinoline alkaloids, a family of natural products showing a wide range of structural diversity and biological and pharmaceutical activity, has been based either on continuation or improvement of known traditional methods or on new, recently developed, strategies. Both diastereoselective and enantioselective catalytic methods have been applied. This review describes the stereochemically modified traditional syntheses (the Pictet-Spengler, the Bischler-Napieralski, and the Pomeranz-Fritsch-Bobbitt) along with strategies based on closing of the nitrogen-containing ring B of the isoquinoline core by the formation of bonds between C1-N2, N2-C3, C1-N2/N2-C3, and C1-N2/C4-C4a atoms. Methods involving introduction of substituents at the C1 carbon of isoquinoline core along with syntheses applying various biocatalytic techniques have also been reviewed.
