We developed a compound library for orally available gonadotropin-releasing hormone (GnRH) receptor antagonists that were based on a uracil scaffold. On the basis of in vitro activity and CYP inhibition profile, we selected 18a (SKI2496) for further in vivo studies. Compound 18a exhibited more selective antagonistic activity toward the human GnRH receptors over the GnRHRs in monkeys and rats, and this
O-arylation of 1,2-aminoalcohols using functionalized triarylbismuthreagents is reported. The reaction can be performed using substoichiometric amounts of copper acetate and operates under mild conditions. Good functional group tolerance is observed, giving access to a range of β-aryloxyamines. The effect provided by the amino group in the arylation reaction is investigated.

A variety of substituted styrenes have been aminohydroxylated using t-butyl carbamate to give either enantiomer of highly enantiomerically enriched N-Boc protected amino alcohols in good yields. Better levels of regioselectivity were observed with (DHQ)(2)PHAL than with (DHQD)(2)PHAL even though the enantioselectivities observed were comparable. One of the amino alcohol products was converted into a novel chiral diamine. (C) 1998 Elsevier Science Ltd. All rights reserved.
