Abstract:
The present invention relates to ring-fused lactam derivatives with diexomethylene groups and a method of their preparation thereof, more particularly to a novel ring-fused lactam derivatives with diexomethylene groups which is prepared by intramolecular acyliminium cyclization of a hydroxylactam having a trimethylsilylmethyl-allene group in the presence of a Lewis acid and is useful as an intermediate for synthesis of other polycyclic compounds by the Diels-Alder reaction, and a method of their preparation thereof.
Abstract:
The present invention relates to tricyclic tetrahydrofuran derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds by performing an intramolecular cyclization of tetrahydrofuran-allene derivatives in the presence of metal catalyst and sodium azide (NaN 3 ).

Abstract:
The present invention relates to sulfonamide derivatives as a serotonin receptor antagonist and serotonin reuptake inhibitor and a pharmaceutically acceptable salt thereof. The sulfonamide derivatives have serotonin 5-HT 2A and 5-HT 2C receptor antagonizing and serotonin reuptake inhibiting functions, and thus may be efficiently applied to a CNS-related disease such as depression, obesity, psychosis, schizophrenia, suicidal tendency, anxiety, obsessional neurosis, migraine, appetite disorders, sleep disorders, stroke, and withdrawal symptoms caused by drug abuse.
Abstract:
The present invention relates to bicyclic tetrahydrofuran derivatives and a preparation method thereof. Particularly the present invention relates to a process of preparing the above compounds by performing an intramolecular cyclization of tetrahydrofuran-allenol derivatives in the presence of alcohol compound, transitional metal catalyst and carbon monoxide.
Abstract:
The present invention relates to N-benzyl-N-(2-dimethylamino-ethyl)-benzenesulfonamide compounds useful for the treatment of central nervous system (CNS) disorders.
Abstract:
The present invention relates to tricyclic tetrahydrofuran lactone derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds 'tetrahydrofuran lactone derivatives' by performing an intramolecular cyclization of tetrahydrofuran-allenic acid derivatives in the presence of a phenyl halide, a palladium catalyst and a base.
Abstract:
Disclosed are isoindolinone derivatives having inhibitory activity against T-type calcium channels, pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition comprising the same as an active ingredient.
Abstract:
Disclosed are cis-2,6-disubstituted tetrahydropyran derivatives and a preparation method thereof. The tetrahydropyran derivatives can be prepared by Prins-reacting tetrahydropyran derivatives with homopargylicalcohol derivatives in the presence of trimethylsilyltriflate. The tetrahydropyran derivatives with cis-substituents at both C2 and C6 positions of the tetrahydropyran ring are useful as intermediates for use in the synthesis and development of therapeutically effective, naturally occurring compounds.
Abstract:
The present invention relates to a novel 1,2-dihydro-1-oxophthalazinyl piperazine compound having biological activity as serotonin receptor antagonist, a preparation method of the compound and a pharmaceutical composition for the treatment and prevention of central nervous system diseases comprising the compound.
Abstract:
The present disclosure relates to an α-aminoamide derivative compound and a pharmaceutical composition containing the same. According to various embodiments of the present disclosure, provided is a therapeutic agent which can overcome the disadvantages of existing drugs used as a MAO-B inhibitor and, specifically, reversibly inhibits MAO-B through a non-covalent bond so as to alleviate or eliminate the side effects of the existing drugs which exhibit a therapeutic effect by irreversibly acting via a covalent bond with MAO-B. Particularly, a new compound having superior stability and efficacy compared to the existing reversible MAO-B inhibitors may be provided.
