Quinolones as gonadotropin releasing hormone (GnRH) antagonists: simultaneous optimization of the C(3)-aryl and C(6)-substituents
摘要:
A series of 3-arylquinolones was prepared and evaluated for their ability to act as gonadotropin releasing hormone (GnRH) antagonists. A variety of substitution patterns of the 3-aryl substituent are described. The 3,4,5-trimethylphenyl substituent (23h) was found to he optimal. (C) 2000 Elsevier Science Ltd. All rights reserved.

New general method for the allylation of aromaticcompounds from allyltrimethylsilane utilizing the combination of iodosylbenzene and BF3 OEt2 are described, which is based upon the umpolung of allyltrimethylsilane by way of cationic allylphenyliodonium (III) salt complex as an intermediate.

The palladium-catalyzed regioselective allylation reaction between chloromethyl(hetero)arenes and allyl pinacolborate is reported in this work. Chloromethylarenes smoothly reacted with allyl pinacolborate, producing para-allylated dearomatization products or para-allylated arenes in satisfactory to good yields. 2-(Chloromethyl)thiophenes and 2-(chloromethyl)furans bearing substituents on the 5-positions

Palladium-catalyzed remote sp2–sp3 coupling reaction of chloromethylarenes with allyltrimethoxysilane is described in this work. The allylation reaction regioselectively occurred on the para-positions of 1-(chloromethyl)naphthalenes and benzyl chlorides to form new C(sp2)–C(sp3) bonds. The reaction proceeds smoothly under mild conditions to produce allyl arenes in moderate to excellent yields.
