Abstract: Optically active 2-hydroxymethyl-3,4-diphosphino-tetrahydrofuran derivative ligands of formula (I) and their borane adducts are new. R1 = H, 1-10C acyl, 1-10C alkyl or 2-10C alkenyl or aryl or aryl-alkylene (both optionally ring-substituted); or SiR4R5R6; R2-R6 = 1-10C alkyl or aryl or aryl-alkyl (both optionally ring-substituted). Also claimed are: (i) transition metal complexes containing (I) as ligands of formula (IV); and (ii) intermediate diphosphino-lactone ligands of formula (III). M = Co, Ir, Ni, Pd, Pt, Rh or Ru; A = ligand (I); L = organic ligand; D = equivalent of a non-coordinated anion; n = 1 or 2; and p, q = 0-4.

Abstract: Optically active fumaric acid diesters of the formula I in which R and R denote hydrogen or an optionally substituted alkyl, cycloalkyl, aralkyl or aryl group; R and R denote an optionally substituted alkyl, cycloalkyl, aralkyl or aryl group or the radical -CO2R , where R stands for hydrogen or a C1-C4-alkyl radical; or R is linked with R and/or R is linked with R to give a 5- or 6-membered, optionally alkyl-substituted heterocycle which can carry a further carbonyl group in the adjacent position to X or Y; X or Y stands for oxygen or the radical -NR and C denotes a centre of asymmetry of R or S absolute configuration and the preparation of the diesters I and their use as dienophiles in asymmetric Diels-Alder reactions.
