The reaction of 2H-1-benzopyran with several 1,3-dipoles gives cycloadducts in good yields. The orientation of the cycloaddition is qualitatively interpreted in terms of FMO theory. These heteropolycyclic compounds were also obtained from hydrazones of 3-aroyl-2H-1-benzopyrans, prepared from 3-cy...
A one-pot synthesis of functionalized 2,2-disubstituted 2H-1-benzopyrans The synthesis of functionalized 2,2-disubstituted 2H-1-benzopyrans was achieved by condensing 2,3,5-trimethylhydroquinone (TMHQ) with α,β-unsaturated ald... Janine,Cossy,and,... - 《Tetrahedron Letters》 被引量: 43发...
A series of benzofuro[3,2-f][1]benzopyrans were screened for their in vitro anti-TB, anti-bacterial and anti-fungal activities by Prado et al. [23]. These compounds seem as promising specific anti-TB agents, since they exhibited neither significant cytotoxicity against mammal cells, nor ...
