The absorption and fluorescence spectra of 2-[4-(dimethylamino)phenyl]-3-hydroxy-4H-chromene-4-one in benzene or toluene and in the presence of methanol (proton donor) or the highly polar dimethylsulfoxide (proton acceptor) were measured and analyzed from the point of view of the potential influence

Regiospecific cyclization of the alcohol &into the bicyclo[ 4.2.21 compound g was achieved via selective activation of the secondary methoxy group and subsequent acid treatment. A side-chain was introduced at the bridge-head position, thus making up the bicyclomycin skeleton. Bicyclomycin, which i
