Patent number: 4918231Abstract: A process for the production of 1,2-amino alcohols, in improved yields, comprising the steps of:(1) reacting a silylated cyanohydrin compound with a Grignard reagent;(2) treating the reaction product of Step 1 with either a reducing agent, or an organolithium compound;(3) hydrolyzing the reaction product of Step 2;(4) isolating the resulting 1,2-amino alcohol.The 1,2-amino alcohols thus formed are useful as pharmaceuticals or precursors therefor.Type: GrantFiled: December 15, 1988Date of Patent: April 17, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventors: Larry R. Krepski, Steven M. Heilmann, Jerald K. Rasmussen

Patent number: RE35128Abstract: The present invention is concerned with the preparation of erythro N-substituted vicinal aminoalcohol derivatives from hydroxyl-protected cyanohydrin derivatives by successive Grignard reaction, transimination using a primary amine, reduction of the resulting imine and removal of the hydroxyl-protecting group. The products are obtained either as a racemate or in an optically pure form, depending upon the stereochemical composition of the cyanohydrin derivatives.Type: GrantFiled: June 7, 1994Date of Patent: December 19, 1995Assignee: Duphar International Research B.V.Inventors: Johannes Brussee, Arne van der Gen, Cornelis G. Kruse

Patent number: RE43844Abstract: A process for making optically pure (R) and (S) salbutamol comprises obtaining the (R) or (S) isomer of either salbutamol or a salbutamol precursor in substantially optically pure form by resolving a racemic or optically impure mixture of enantiomers of salbutamol or of said precursor with either (L) or (D) tartaric acid, and where necessary converting said isomer of said precursor into either (R or (S) salbutamol respectively; then optionally converting said optically pure (R) and/or (S) salbutamol into a pharmaceutically acceptable salt.Type: GrantFiled: December 10, 2001Date of Patent: December 4, 2012Assignee: Cipla LimitedInventors: Yusuf Khwaja Hamied, Rajendra Narayanrao Kankan, Dharmaraj Ramachandra Rao
