  • Patent number: 6610866
    Abstract: A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.

  • Patent number: 6362254
    Abstract: An activated, substantially water soluble poly(ethylene glycol) is provided having of a linear or branched poly(ethylene glycol) backbone and at least one terminus linked to the backbone through a hydrolytically stable linkage, wherein the terminus is branched and has proximal reactive groups. The free reactive groups are capable of reacting with active moieties in a biologically active agent such as a protein or peptide thus forming conjugates between the activated poly(ethylene glycol) and the biologically active agent.

  • Publication number: 20020019572
    Abstract: The present invention provides a method for alkoxylating organic compounds comprising contacting an organic compound adapted to be alkoxylated with an alkylene oxide in a reaction vessel under conditions effective to alkoxylate the organic compound. The alkylene oxide is maintained in vapor form during transport to said reaction vessel, during discharge into said reaction vessel, and during contacting of the organic compound with the alkylene oxide. The result is an alkoxylated product containing less flocculant.
