The present invention relates to non-steroidal progesterone receptor modulators of the general formula 1,
the use of the progesterone receptor modulators for the manufacture of medicaments, and pharmaceutical compositions which comprise these compounds.
The compounds according to the invention are suitable for the therapy and prophylaxis of gynaecological disorders such as endometriosis, leiomyomas of the uterus, dysfunctional bleeding and dysmenorrhoea, and for the therapy and prophylaxis of hormone-dependent tumours and for use for female fertility control and for hormone replacement therapy.

A dual Cu/Ni catalytic system is identified for linear selective hydroalkylation of vinylarenes with complementary regioselectivities to similar catalytic systems. Turnover numbers (TONs) with respect to Ni are as high as 72, and Cu is revealed to accelerate the rate of formation of the linear alkyl nickel intermediate. Examples for the diversification of pharmaceuticals are also demonstrated.

The existing methods, including electrophilic aromatic substitution and C–H activation, often require harsh reaction conditions and excess pyridine and generate multiple regioisomers. Herein, we report a method for borane-catalyzed tandem reactions that result in exclusively C3-selective alkylation of pyridines. These tandem reactions consist of pyridine hydroboration, nucleophilicaddition of the resulting
