Photoinduced Synthesis of New Diisochromenochromen-4-ones and Their Antimicrobial Activities [PDF]

open access: yes, 2012
The diisochromenochromen-4-one 3a-3b, 4a-4c, 5a-6a  & 7 have been prepared from the photocyclization reaction of bischromen-4-one 2a-2e. The later compounds are obtained from the O-alkylation of the suitable 3-hydroxy-2-aryl-4H-chromen-4-one 1a-1e with 4,

Oxobenzo[f]benzopyrans as new fluorescent photolabile protecting groups for the carboxylic function [PDF]

open access: yes
The properties of three oxobenzo[f]benzopyrans as new fluorogenic photolabile protecting groups for the carboxylic function of amino acids were studied. Fluorescent amino acid conjugates were efficiently prepared and characterised.
