19 Mar 1992TL;DR: In this article, the authors defined a class of antidepressant agents having formula (I), wherein R1 is a polycycloalkyl group, R2 is methyl or ethyl, X is O or NH, and Y comprises a 5- or 6-membered heterocyclic ring having one or two nitrogens.
Abstract: Antidepressant agents having formula (I), wherein R1 is a polycycloalkyl group; R2 is methyl or ethyl, X is O or NH; and Y comprises a 5- or 6-membered heterocyclic ring having one or two nitrogens; or fused bicyclic heterocyclic rings having a total of three nitrogen atoms, one in each ring and one angular nitrogen.

14 Mar 2000TL;DR: In this paper, the present invention relates to bicyclic heterocyclic compounds of general formula (I), wherein Ra to Rd, A to D and X are defined as in claims 1 to 8, the tautomers, stereoisomers and salts thereof, particularly the physiologically acceptable salts thereof with inorganic or organic acids or bases which have valuable pharmacological properties.
Abstract: The present invention relates to bicyclic heterocyclic compounds of general formula (I), wherein Ra to Rd, A to D and X are defined as in claims 1 to 8, the tautomers, stereoisomers and salts thereof, particularly the physiologically acceptable salts thereof with inorganic or organic acids or bases which have valuable pharmacological properties, particularly an inhibitory effect on signal transduction mediated by tyrosine kinases, their use in treating diseases, particularly tumour diseases, diseases of the lung and airways and the preparation thereof.

TL;DR: Novel routes toward both enantiomers of the bicyclic proline surrogate 2-carboxy-6-hydroxyoctahydroindole, i.e., Choi, were developed on the basis of the oxidative cyclization of L-tyrosine, but synthesis of the proposed sequence of (+)-aeruginosin 298-A did not provide the natural product.

TL;DR: In the presence of 10 mol % Cp*Ru(cod)Cl, 1,6-diynes with a tertiary center at 4-position reacted with various isothiocyanates at their C=S double bond to afford bicyclic (2H)-thiopyranimines in 35-88% yields.
Abstract: In the presence of 10 mol % Cp*Ru(cod)Cl, 1,6-diynes with a tertiary center at 4-position reacted with various isothiocyanates at their CS double bond to afford bicyclic (2H)-thiopyranimines in 35−88% yields. The (2H)-thiopyran structure was unequivocally determined by X-ray analysis. The cycloaddition of carbon disulfide with a diyne similarly gave the expected bicyclic dithiopyrone in 50% yield.
