Abstract:
PURPOSE: An oxaspiro compound and a method for preparing the same are provided to be used as an intermediate in a natural product or novel drug synthesis. CONSTITUTION: An oxaspiro compound is denoted by chemical formula 1. In chemical formula 1, R1 and R2 are hydrogen, alkyl group of C1-C6, halogen, nitro, alkyl of C1-C6, or substituted or non-substituted phenyl group as a substituent of C1-C6 alkoxy. The oxaspiro compound of chemical formula 1 is prepared by reacting a carbo compound of chemical formula 3 with methylene cycloalkandiol of chemical formula 2 under the presence of lewis acid. The reaction solvent is dichloro methane. Trimethylsilyl trifluoromethansulfonate(TMSOTf) is used as the lewis acid.
Abstract:
PURPOSE: A pyrazolylmethylamine-piperazine derivative which is effective as a calcium ion channel modulator is provided to ensure effective activation as an T-type calcium ion channel antagonist and to use as an agent for preventing and treating brain diseases, heart diseases and pain diseases. CONSTITUTION: A pyrazolylmethylamine-peperazine derivative is denoted by chemical formula 1. A pharmaceutical composition for preventing and treating brain diseases, heart diseases or pain diseases by T-type calcium ion channel antagonism contains the pyrazolylmethylamine-peperazine derivative of chemical formula 1 or its pharmaceutically acceptable salt an active ingredient. The brain disease is epilepsy, depression, Parkison's disease, dementia or somnipathy. The heart disease is hypertension, cardiac arrhythmia, myocardial infarction, or congestive failure. The pain disease is chronic pain, acute pain, or neurogenic pain. The pyrazolylmethylamine-peperazine derivative is prepared by binding pyrazolylmethylamine compound of chemical formula 3 with piperazine acetyl halide compound of chemical formula 2.
Abstract:
A method for manufacturing a tetrahydropyran derivative is provided to produce an intermediate for synthesizing functional natural material using a homopropagylic alcohol derivative and aldehyde compound. A tetrahydropyran derivative having cis-substituent on C2 and C6 is denoted by the chemical formula 1. In the chemical formula 1, R1 and R2 are separately C1-C6 alkyl group, C6-C15 aryl C1-C6 alkyl group, or C6-C15 aryl group. A method for manufacturing the tetrahydropyran derivative comprises a step of performing prince reaction of aldehyde compound of the chemical formula 3 with homopropagylic alcohol derivative of the chemical formula 2 to produce dihydropyran-3-ilyden triplate compound of the chemical formula 1a.
