标 题 :Process for the solid state synthesis of enantiopure B-aminoalcohols from racemic epoxides
发明人：KAKULAPATI RAMA RAO; NANDURI BHANUMATHI; ELETI RAJENDER REDDY
权利人:COUNCIL SCIENT IND RES
摘要:The invention relates to a process for the solid state synthesis of enantiopure β-aminoalcohols by preparing inclusion complexes of aryloxyepoxide with cyclodextrin by adding an epoxide in equimolar ratio in an organic solvent to an aqueous solution of cyclodextrin, reacting the cyclodextrin complex of aryloxyepoxide with a nucleophile in solid state by intimately grinding the mixture using a mortar and pestle, continuing the mixing till the starting epoxide disappeared on tic, removing excess amines under vacuum, extracting the β-aminoalcohols produced with a solvent with yields of more than 50% and enantioselectivity of upto 100%.
