AUXILIARY SILICON IN REGIOSELECTIVE COBALT CATALIZED PROTOBERBERINE SYNTHESES

eta5-Cyclopentadienyl dicarbonyl cobalt catalyzes the cocyclization of 1,2-bis(propargyl)-1,2,3,4-tetrahydroisoquinolines 4b and 5 with alkynes to provide a novel synthetic entry into the tetrahydroprotoberberine nucleus.By judicious choice of trimethylsilyl substituents, regiocontrol in the D-ring can be achieved.Reaction of 4b with benzonitrile in the presence of the catalyst furnishes the rare isoquino<2,1-b>-2,6-naphthyridine framework, also regioselectively.

C-3 functionalization of indole derivatives with isoquinolines

The literature on the syntheses of substituted 1-(indol-3-yl)-1,2,3,4-tetrahydroisoquinoline derivatives is reviewed. Two main synthetic procedures have been applied for these syntheses. One is cross-dehydrogenative coupling, which can furnish various C-3 functionalized indoles; oxidants and/or catalysts are usually needed. Another convenient synthetic method is the aza-Friedel-Crafts alkylation of indole derivatives with dihydroisoquinoline, the main advantage of this being the direct catalyst-free coupling under mild experimental conditions. The review also considers miscellaneous reactions, where the isoquinoline skeleton is achieved in one of the final steps of the synthesis.

Development of a Cross-Conjugated Vinylogous [4+2] Anionic Annulation and Application to the Total Synthesis of Natural Antibiotic (¡À)-ABX

The cross-conjugated vinylogous [4+2] anionic annulation has been newly developed, the cascade process of which has a high preference for regiochemical control and chemoselectivity, giving rise to exclusively Michael-type adducts in moderate to high yields (up to 94 %, 35 examples). By making use of this approach as a key operation, the first total synthesis of natural antibiotic ABX, in racemic form, has been successfully achieved in a concise 7-step sequence with an overall yield of about 20 %.

Synthesis and conformational analysis of naphth[1,2-e][1,3]oxazino[4,3-a][1,3]isoquinoline and naphth[2,1-e][1,3]oxazino[4,3-a]isoquinoline derivatives

Through the cyclization of 1-(beta-hydroxynaphthyl)-1,2,3,4-tetrahydroisoquinoline and 1-(alpha-hydroxynaphthyl)-1,2,3,4-tetrahydroisoquinoline with formaldehyde, phosgene, p-nitrobenzaldehyde or p-chlorophenyl isothiocyanate, 8-substituted 10,11-dihydro-8H,15bH-naphth[1,2-e][1,3]oxazino[4,3-a]isoquinolines (3 and 4) and 10,11-dihydro-8H,15bH-naphth[2,1-e][1,3]oxazino[4,3-a]isoquinolines (15 and 16) were prepared. Conformational analysis of both the piperidine and the 1,3-oxazine moieties of these heterocycles by NMR spectroscopy and an accompanying theoretical study revealed that these two conformationally flexible six-membered ring moieties prefer twisted chair conformers.

Synthesis of new praziquantel analogues: Potential candidates for the treatment of schistosomiasis

An efficient synthesis of antischistosomal drug praziquantel and analogues was achieved and the synthetic route designed was to afford structurally diverse analogues for better structure-activity relationship understanding. Total of nineteen PZQ analogues with structural variations at amide, piperazine and aromatic moieties have been synthesized and fully characterized. Among all the new analogues tested for antischistosomal activity, one dimethoxy tetrahydroisoquinoline analogue and two tetrahydro-beta-carboline analogues exhibited moderate activity against adult Schistosoma mansoni. Tetrahydro-beta-carboline analogues showed moderate activity whereas the presence of p-trifluoromethylbenzoyl and p-toluenesulphonyl moieties resulted in complete suppression of antischistosomal activity.
