Synthesis of benzo-fused lactams and lactones via Ru(II)-catalyzed cycloaddition of amide- and ester-tethered alpha,omega-diynes with terminal alkynes: Electronic directing effect of internal conjugated carbonyl group

In the presence of a catalytic amount of Cp*RuCl(cod), 1,6- and 1,7-diynes connected by an amide or an ester tether underwent cycloaddition with terminal alkynes at room temperature to give rise to cycloadducts in 40-93% yields with 63 : 37-83 : 17 regioisomer ratios.

4-SUBSTITUTED 4, 6-DIALKOXY-CINNOLINE DERIVATIVES AS PHOSPODIESTERASE 10 INHIBITORS FOR THE TREATMENT OF PSYCHIATRIC OR NEUROLOGICAL SYNDROMS

The present disclosure relates generally to the field of phosphodiesterase 10 (PDE10) enzyme inhibition by cinnoline compounds of Formulas:(I) and (II); wherein R’-R3 and R15 -R18 are as defined herein. Still further, the present invention provides methods for synthesizing compounds with such activity and selectivity, as well as methods of and corresponding pharmaceutical compositions for treating a patient, e.g., mammals, including humans, in need of PDE inhibition. Treatment is preferably for a disease state that involves elevated intracellular PDE10 levels or decreased cAMP and/or cGMP levels, e.g., involving neurological or psychiatric syndromes, especially those states associated with psychoses, most especially schizophrenia or bipolar disorder, obsessive-compulsive disorder, and/or Parkinson’s disease. In particular, such psychoses, obsessive-compulsive disorder, and/or Parkinson’s disease arc due at least in part to catabolism of intracellular cAMP and/or cGMP levels by PDE 10 enzymes or where such an impaired condition can be improved by increasing cAMP and/or cGMP levels

Oxydative Aryl-Aryl-Verknuepfung von 6,6′,7,7′-Tetramethoxy-1,1′,2,2′,3,3′,4,4′-octahydro-1,1′-biisochinolin-Derivaten

We described the synnthesis of 2 by intramolecular oxidative coupling of 1,1′-biisoquinoline derivatives 1 (Scheme 1).This heterocyclic system can be considered as a union of two apomorfine molecules and may thus exhibit dopaminergic activity. – The readily available tetrahydrobiisoquinoline 6 was methylated to 11 (Scheme 4) and reduced (with NaBH3CN) to rac-7 and (catalytically) to meso-7 (Scheme 3).Reduction of 11 NaBH4 and the biurethane rac-9 with LiAlH4/AlCl3 afforded meso- and rac-10, respectively (Scheme 4).Demethylation of 6, meso-10,meso and rac-7 led to 12, meso-14, meso- and rac-13, respectively (Scheme 5).The latter two phenols were converted with chloroformic ester to the hexaethoxycarbonyl derivatives meso- and rac-15 and subsequently saponofied to the biurethanes meso- and rac-16, respectively (Scheme 5). – In order to assure proximity of the aromatic rings, the ethano-bridged derivatives meso- and rac-18 were prepared by condensing meso- and rac-7 with oxalic ester and reducing the oxalyl derivatives meso- and rac-17 with LiAlH4/AlCl3, respectively (Scheme 6).The 1H-NMR. spectra at different temperatures showed that rac-18 populated two conformers but rac-17 only one, all with C2-symmetry, and that meso-17 as well as meso-18 populated two enantiomeric conformers with C1-symmetry.Whereas both oxalyl derivatives 17 were fairly rigid due to the two amide groupings, the ethano derivatives 18 exhibited coalescence temperatures of -20 and 30 deg. – The intra, molecular coupling of the aromatic rings was sucessful under ‘ non-phenolic oxidative’ conditions with the tetamethoxy derivatives 7, 10 and 18, the rac-isomers leading to the desired dibenzophenanthrolines, the meso-isomers, however, mostly to dienones (Scheme 9): With VOF3 and FSO3H in CF3COOH/CH2Cl2 rac-7 was converted to rac-19, rac-18 to rac-21 and rac-10 to a mixture of the rac-20 and the dienone 23b of the morfinane type.Under the same conditions meso-10 was transformed to the dienone 23a of the morphinane type, whereas meso-18 yielded the dienone 24 of the neospirine type, both in lower yields.The analysis of the spectral data of the six coupling products offers evidence for their structures.With the demethylation of rac-20 and rac-21 to rac-25 and rac-26, respetivly, the synthetic goal of the wor was reached, but only in the rac-series (Scheme 10). – In the course of this work two cleavages of octahydro-1,1′-biisoquinolines at the C(1), C(1′)-bond were observed: 1) The biurethanes 9 and 16 in both the meso- and rac-series reacted with oxygen in CF3COOH solution to give the 3,4-dihydroisoquinolinium salts 27 and 28; the latter was protonated to the quinomethide 30 (Scheme 11). 2) Under the Clarke-Eschweiler reductive-methylation conditions meso- and rac-7 were cleaved to the tetrahydroisoquinoline derivative 32.

Three-component coupling reactions of isoquinolines, dimethyl acetylenedicarboxylate and indoles: a facile synthesis of 3-indolyl-1,2-dihydro-2-isoquinolinyl-2-butenedioate

A three-component coupling of isoquinolines, dimethyl acetylenedicarboxylate (DMAD) and indoles is achieved for the first time to produce dimethyl (E)-2-[1-(1H-3-indolyl)-1,2-dihydro-2-isoquinolinyl]-2-butenedioates in excellent yields and with high selectivity. The reaction proceeds smoothly at room temperature without a catalyst. Quinoline, DMAD and indole also undergo smooth coupling to furnish dimethyl (E)-2-[2-(1H-3-indolyl)-1,2-dihydro-1-quinolinyl]-2-butenedioate under similar conditions. This method is very useful to functionalize both indoles and aza-aromatic compounds in a one-pot operation.

External-Photocatalyst-Free Visible-Light-Mediated Synthesis of Indolizines

A visible-light-mediated synthesis of valuable polycyclic indolizine heterocycles from easily accessed brominated pyridine and enol carbamate derivatives has been developed. This process, which operates at room temperature under irradiation from readily available light sources, does not require the addition of an external photocatalyst. Instead, an investigation into the reaction mechanism indicates that the indolizine products themselves may be in some way involved in mediating and accelerating their own formation. Preliminary studies also show that these simple heterocyclic compounds may be capable of facilitating other visible-light-mediated transformations.
