Page/Page column 22; 23, (2015/08/03)
Compounds of the formula A-X-Y-B and compositions are described which are useful especially for treatment of angiogenesis-related diseases or disorders such as neovascularisation of the eye, age- related macular degeneration, diabetic retinopathy or cancer, wherein A is a six membered heteroaryl ring containing 2 nitrogen atoms which is optionally substituted with R1; R1 is H, CI-6 alkyl, CN, CONR2R3; R2 and R3 which may be the same or different and selected from H, CI-6 alkyl or R2 and R3 form a ring; the group X-Y is an alkyne or alkene, in the case wherein X-Y is an alkene the double bond may be cis or trans and optionally substituted with R1 B is an aryl; or five or six membered heteroaryl ring containing 1 to 3 heteroatoms, both of which may optionally substituted with one or more R4; R4 is R1 or OR5; R5 is H, COR6 or R6; and R6 is CI-6 alkyl and salts thereof.

Lewis-acid-catalyzed benzylic reactions of 2-methylazaarenes with aldehydes have been investigated. Series of azaarene derivatives were afforded by this reaction. 2-(Pyridin-2-yl)ethanols with common substituents were formed through the LiNTf2-promoted aldol reaction for the first time. 2-Alkenylpyridines, exclusively in the form of the E isomers, were synthesized in the presence of LiNTf2 cooperated with H2NTf. In the presence of La(Pfb)3 as catalysis, 2-alkenylquinolines were obtained in high yields through the reactions between 2-methylquinolines and aldehydes under air.
Hypervalent iodine mediated oxidative cyclization of o -hydroxystilbenes into benzo- and naphthofurans
Singh, Fateh V.,Wirth, Thomas
experimental part, p. 1171 - 1177 (2012/05/20)
A new and convenient metal-free cyclization of ortho-hydroxystilbenes into 2-arylbenzofurans and 2-arylnaphthofurans mediated by hypervalent iodine reagents is described. The cyclization products are isolated in good to excellent yields using stoichiometric (diacetoxyiodo)benzene in acetonitrile. Georg Thieme Verlag Stuttgart New York.
