    monomers. Ring-opening homopolymerisation and copolymerisation of the IPTA monomer, derived from l-ascorbic acid, with d,l-lactide have been performed. The polymers were characterised by elemental microanalysis, as well as IR and (1)H and (13)C NMR spectroscopies. GPC was used to estimate product molecular weights, and thermal studies (DSC and TGA) revealed that all the polymers were amorphous, being

    A highly regio- and stereoselective Diels-Alder reaction between dienophiles of type I and dienes of type II (Scheme 1) gives rise to Diels-Alder adducts of type III. Upon treatment with BF3.Et2O, these adducts are smoothly converted into the corresponding enones (Scheme 6). Under mild acidic conditions, enone (±)-33 gave bicyclic diketone (±)-34via an intramolecular Michael-type addition. Diketone

    [PtMe3(H2O)(2)}(2)SO4] (1) reacts with 1-amino-1-deoxy-D-glucitol (C2), 1-(N-methylamino)-1-deoxy-D-glucitol (C3) and 2-amino-2-deoxy-alpha-D-glucose (C4) in diluted aqueous solution to give platinum(IV) carbohydrate complexes of the type [PtMe3L](2)SO4 (2, L = C2; 3, L = C3; 4, L = C4). The complexes were characterized by microanalysis, H-1, C-13 and Pt-195 NMR spectroscopy. In aqueous solution the amino glucitols in 2 and 3 are tridentately (kappa(3)N,O-2,O-4) Or bidentately (kappa(2)N,O-2) coordinated by replacing the C4-OH ligand by water. [PtMe3(H2O)(2)}(2)SO4] (1) reacts with stoichiometric amounts of sodium 2-amino-2-deoxy-D-gluconate (C5Na), sodium D-gluconate (C6Na) and calcium O-isopropylidene-D-threonate (C7Ca) to give complexes of the type [PtMe3L] (5, L = C5; 6, L = C6) and [PtMe3L(H2O)] (7, L = C7), respectively. The complexes were isolated as colorless, air-stable powders and fully characterized by microanalysis,H-1, C-13 and Pt-195 NMR spectroscopy. The ligands in 5-7 are deprotonated sugar acids that are facial tridentately (kappa(3)O(1,4),N-2 5; kappa(3)O(1,2,4) 6) and bidentately (kappa(2)O(1,2) 7) coordinated, respectively. In aqueous solutions of 5 and 6 water may be coordinated at platinum instead of the hydroxyl group at C4. (C) 2000 Elsevier Science S.A. All rights reserved.
