, (2008/06/13)
A compound of formula (I) where D is a VLA-4 specificity determinant which does not impart significant IIB/IIIa activity; R41 is a group of the formula (V): U - (CH2)d - V - T wherein U is selected from oxygen, sulphur, a direct bond or —CH2O—, V is selected from nitrogen, oxygen, sulphur, S(O), S(O)2 or a direct bond, d is zero or a number from 1 to 4, and T is selected from a range of variables defined in the application; and other variables are defined in the application, or a pharmaceutically acceptable salt or in vivo hydrolysable derivative thereof. The compounds are useful in the treatment of disease mediated by the interaction between VCAM-1 and/or fibronectin and the integrin receptor α4β1. Pharmaceutical compositions and methods of use or treatment are also described and claimed.
Enzymes in organic synthesis, 26: Synthesis of enantiomerically enriched 2,3- and 3,4-dimethylpentan-5-olides by lipase-catalyzed regio- and enantioselective alcoholysis of cis- and trans-2,3-dimethylpentanedioic anhydrides

The enzyme-catalyzed regio- and enantioselective alcoholysis of racemic cis- and trans-2,3-dimethylpentanedioic anhydride in the presence of Novozym 435 from Candida antarctica afforded two of the eight possible monoesters with an enantiomeric excess higher than 90%. Regioselective reductions of these monoesters with lithium borohydride or borane/dimethyl sulfide furnished four enantiomerically highly enriched dimethylpentan-5-olides, which are versatile chiral intermediates.
