A full overview of the decarboxylative cross-coupling reaction between heteroaromatic carboxylic acids and aryl halides is described. This transformation employs palladium catalysts with short reaction times providing facile synthesis of aryl-substituted heteroaromatics. The effect of each reaction parameter including solvent, base, and additive employed as well as the full substrate scope of this

The invention relates to FSH receptor antagonist according to general formula (I) or a pharmaceutically acceptable salt thereof and to a pharmaceutical composition containing the same. The compounds can be used for the treatment and prevention of endometriosis, for the treatment and prevention of pre-menopausal and peri-menopausal hormone-dependent breast cancer, for contraception, and for the treatment of uterine fibroids and other menstrual-related disorders.
The silver(I)-promoted oxidative cyclization of homopropargylamines at room temperature provides a novel access to pyrroles. Homopropargylamines are readily available by the addition of a propargyl Grignard reagent to Schiff bases.
