  • MODIFICATION OF AMINES AND ALCOHOLS
    Publication number: 20090111980
    Abstract: A process for the modification of amines and alcohols, comprising (i) providing a substrate having amino groups or alcohol groups, wherein said substrate is, e.g., a polysaccharide; (ii) providing a modifying agent which is a lactone, an ester, a polyester, a carbonate, a polycarbonate, a lactide, a glycolide, an anhydride, an acid, a thioester or a carbamate; (iii) providing a catalyst which is, e.g., a amino acid or an organic acid; and (iv) reacting the substrate with the modifying agent in the presence of the catalyst.

  • Synthesis of B-keto esters
    Patent number: 6642035
    Abstract: &bgr;-keto esters are prepared by way of a lipase-catalyzed transesterification. The synthetic methodology provides a simple scheme for the synthesis of optically active &bgr;-keto esters that are useful building blocks and starting materials for natural product synthesis. Moreover, the methodology employs mild, solvent-free conditions. The methodology may also be employed for resolving racemic alcohols.
