Article: Photochemical approach to naphthoxazoles and fused heterobenzoxazoles from 5-(phenyl/heteroarylethenyl)oxazoles.[show abstract] [hide abstract]
ABSTRACT: A new synthetic approach is presented for the synthesis of naphthoxazoles and fused heterobenzoxazoles. The starting 5-(aryl/furyl/thienyl/pyridyl ethenyl)oxazoles are prepared from the corresponding α,β-unsaturated aldehydes using Van Leusen reagent in very good yields and are transformed into naphthoxazoles and fused heterobenzoxazoles on irradiation under aerobic conditions and in the presence of iodine.The Journal of Organic Chemistry 03/2011; 76(8):2904-8. · 4.45 Impact Factor
Article: Synthesis and photochemistry of 2‐styrylpyrroles. Intermolecular photoaddition of pyrroles to a double bond[show abstract] [hide abstract]
ABSTRACT: Irradiation of the 2-styrylpyrroles 3 and 5 resulted in intermolecular addition of the pyrrole derivative to the double bond of a second molecule in a regiospecific way to give the dimeric products 6 and 7 as the main products. The N-methyl-substituted derivative 4 did not show the same reaction, but reacts as the corresponding furan derivative.Recueil des Travaux Chimiques des Pays-Bas. 09/2010; 114(11‐12):476 - 479.
