Patent number: 6342645Abstract: The present invention relates to methods for the production and isolation of D-chiro-inositol (DCI) from kasugamycin. More specifically, the present invention relates to a method of producing DCI by hydrolysis of kasugamycin with aqueous trifluoroacetic acid in the presence of a strongly acidic ion exchange resin. The present invention further relates to methods of isolating DCI from an aqueous mixture, such as a hydrolysis mixture, either directly or by forming an organic derivative of DCI.Type: GrantFiled: December 29, 2000Date of Patent: January 29, 2002Assignee: Insmed Pharmaceuticals, Inc.Inventors: Robert Plourde, Jr., Mark C. Sleevi, Rachel K. Longo

Patent number: 6310262Abstract: A new process prepares retiferol derivatives of formula I: wherein A is —C ≡C— or —CH═CH—, and R1 and R2 are independently of each other lower alkyl or lower perfluoroalkyl, one version couples ketones of formula 1I with compounds of formula III A second version couples phosphinoxides of formula IV with aldehydes of formula V. Compounds of formula I are useful in the treatment or prevention of hyperproliferative skin diseases and for reversing the conditions associated with photodamage.Type: GrantFiled: October 3, 2000Date of Patent: October 30, 2001Assignee: Basilea Pharmaceutica AGInventor: Hans Hilpert

Patent number: 6211419Abstract: A method for operating an epoxide containing system which contains a catalyst is disclosed. The method comprises feeding carbon dioxide to the epoxide containing system at an amount of from 0.01 to 5.0 weight percent; and maintaining the epoxide containing system at a temperature of from 100° C. to 150° C. The catalyst has a half life of at least 40 days at 120° C. The present invention allows anion exchange resins in the bicarbonate form to be used for the hydrolysis of ethylene oxide at temperatures exceeding 100° C. The rate of catalyst swelling is minimized and lifetime of the catalyst enhanced.Type: GrantFiled: April 24, 2000Date of Patent: April 3, 2001Assignee: The Dow Chemical CompanyInventors: Gary R. Strickler, Von G. Landon, Guo-Shuh John Lee
