The Rh4(CO)12-catalyzed hydroformylation at low temperature (40°C) of the 1-, 2- and 3-vinylpyrrole gives the corresponding branched aldehydes 2-(1-pyrrolyl)propanal, 2-(2-pyrollyl)propanal and 2-(3-pyrrolyl)propanal with high α-regioselectivity.
The present invention relates to compounds of Formula (I)
and their pharmaceutically acceptable salts, wherein the substituents are as described herein, and their use in medicine, in particular as Trk antagonists.
