A generalstudy of the regioselectivehydroamination of terminalalkynes in the presence of [(eta5-Cp)2Ti(eta2-Me3SiC2SiMe3)] (1), [(eta5-CpEt)2Ti(eta2-Me3SiC2SiMe3)] (CpEt=ethylcyclopentadienyl) (2), and [(eta5-Cp*)2Ti(eta2-Me3SiC2SiMe3)] (Cp*=pentamethylcyclopentadienyl) (3) is presented. While aliphatic amines give mainly the anti-Markovnikovproducts, anilines and aryl hydrazines yield the Markovnikov

(EN) This invention relates to a series of arylsubstituted piperazines, of Formula (I), pharmaceutical compositions containing them and intermediates used in their manufacture. The compounds of the invention selectively inhibit binding to the $g(a)-1a adrenergic receptor, a receptor which has been implicated in benign prostatic hyperplasia. As such the compounds are potentially useful in the treatment of this and other disease.(FR) L'invention concerne une série de pipérazines à substitution aryle, de formule (I) et des compositions pharmaceutiques renfermant ces pipérazines ainsi que des intermédiaires utilisés dans leur élaboration. Les composés décrits inhibent de manière sélective la liaison sur adrénorécepteur $g(a)-1a, un récepteur intervenant dans l'adénome prostatique. En tant que tels, lesdits composés ont une utilité potentielle dans le traitement de l'adénome considéré et d'autres affections.

A compound of formula (1) or a pharmaceutically acceptable salt thereof:
wherein:
R, is hydrogen, C1-6 alkyl, C1-6 alkoxy or halogen;
R2 and R3 are both hydrogen or together represent a bond;
R4 is selected from C1-6 alkyl, phenyl, phenyl-C1-4 alkyl, CORe where R8 is hydroxy, C1-6 alkoxy or NR9R10 where R9 and R10 are independently hydrogen or C1-4 alkyl and CH2OR11 where R11 is hydrogen, C1-4 alkyl or C1-4 alkanoyl;
R6 is hydrogen, C1-6 alkyl or phenyl C1-4 alkyl;
R6 is phenyl C1-7 alkyl in which the phenyl moiety is optionally substituted by one or two of halogen, ortho-nitro. meta-or para-methoxy, methyl or NR12R13 wherein R12 and R13
are independently hydrogen or C1-6 alkyl or R12 and R13 together are C2-6 polymethylene or the phenyl moiety is 3,4- disubstituted by methylenedioxy or ethylenedioxy; and
R7 is hydrogen or C1-4 alkyl, processes for its preparation and its use as a pharmaceutical.
