Chiral tertiaryphosphines were synthesized by asymmetric hydrophosphination of aromatic enones catalyzed by an organopalladium complex with high yields and stereoselectivity. The procedure offers practical access to chiral tertiaryphosphines.
Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C-6-C-3-C-6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.All the synthesized compounds were evaluated for in vitro cytotoxicity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines. Compound 68 was found to be the most potent showing broad spectrum of cytotoxicity against all the cell lines .
