Novel synthesis and functionalization of ortho–ortho disubstituted biphenyls and a highly condensed novel heterocycle using radical cyclization reaction
This paper describes a novel synthetic route for the preparation of ortho–ortho disubstituted biphenyls and compounds possessing highly condensed ring system represented by structuresX and Y, respectively. Several approaches, such as intermolecular Grubb's olefin metathesis, Heck and, Suzuki reactions were incorporated to functionalize the core structures of X and Y making it suitable for the preparation
It is intended to provide a novel azabicyclo compound which exhibits both HSP90 inhibitory activity and cell proliferation inhibitory effect. Specifically disclosed is a compound represented by the following general formula (I) or a salt thereof: wherein X
1
represents CH or N; any one of X
2
, X
3
and X
4
represents N, and the others represent CH; any one or two of Y
1
, Y
2
, Y
3
and Y
4
represent C—R
4
, and the others are the same or different and represent CH or N; R
1
represents an optionally substituted monocyclic or bicyclic unsaturated heterocyclic group having 1 to 4 heteroatoms selected from N, S and O; R
2
represents an alkyl group having 1 to 6 carbon atoms, or the like; and R
3
and R
4
represent —CO—R
