The present invention relates to compounds of the formula (I) wherein A, Y, Z, R20 to R22 and R50 have the meanings indicated in the claims, which are valuable pharmaceutical active compounds. Specifically, they are inhibitors of the endothelial differentiation gene receptor 2 (Edg-2, EDG2), which is activated by lysophosphatidic acid (LPA) and is also termed as LPA1 receptor, and are useful for the treatment of diseases such as atherosclerosis, myocardial infarction and heart failure, for example. The invention furthermore relates to processes for the preparation of the compounds of the formula (I), their use and pharmaceutical compositions comprising them.

Here we describe a ruthenium-catalyzed regioselective hydrohalogenation reaction of alkynes under mild conditions. Commercially simple halogen sources such as KI, ZnBr2, and ZnCl2 were employed to achieve this transformation. Alkynes derived from bioactive molecules such as l-(−)-borneol, l-menthol, and estrone were also suitable for the transformation, demonstrating the potential synthetic value of
