Ortho-alkynyl biaryls react in the presence of catalytic amount of Br?nsted acids to give phenanthrenes in high yields under mild conditions. The activity and selectivity of this transformation are governed by the substitution pattern of the diarylalkyne moiety. Selectivity shifts are observed between the carbophilic Lewis and Br?nsted acid-catalyzed cycloisomerization involving alkyne activation. (Figure presented.).

A palladium-catalyzed cross-dehydrogenative coupling of phenanthrenes with simple arenes was developed. This protocol provides an opportunity for producing π-extended polycyclic aromatic hydrocarbons with minimum waste and high atomic efficiency under mild and ligand-free conditions.

Kamal, Ahmed,Sreekanth, Kokkonda,Kumar, P. Praveen,Shankaraiah, Nagula,Balakishan,Ramaiah, M. Janaki,Pushpavalli,Ray, Paramita,Bhadra, Manika Pal
experimental part, p. 2173 - 2181 (2010/06/17)
New phenanthrylphenol-pyrrolobenzodiazepine (PP-PBD) conjugates have been synthesized and evaluated for their biological activity. One of the compounds 4a has been evaluated for its antiproliferative activity on 57 human tumour cell lines. The growth inhi
