the ligand environment around the metal center dictates the regiochemical outcome. Markovnikov hydrofunctionalization products are obtained under mild ligand‐free conditions, with up to 99 % yield and >20:1 selectivity. Alternatively, anti‐Markovnikov products can be accessed with a novel 4,4‐disubstituted Pyrox ligand in excellent yield and >20:1 selectivity. Both electronic and stericeffects on the

The invention relates to compounds of formula (I) wherein Ra is —C(O)ORI, in which R1 is 1-7C-alkyl. 3-7C-cycloakyl, 1-7C-alkyl substituted by Raa, or 2-7C-alkyl substituted by Rab and Rac on different carbon atoms, Rb is -T-Q, in which T is 1-6C-alkylene or 3-7C-cycloalkylene, and Q is substituted by Rba and Rbb and Rbc, and is phenyl, which are useful for the therapy of hyperproliferative diseases, in particular human cancer.
Compounds of a certain formula (I), in which Ra and Rb have the meanings indicated in the description, are novel effective compounds with anti-proliferative and apoptosis inducing activity.
