The synthesis of natural 3′,3′′′-binaringenin and four related biflavonoids was performed in good overall yield (15-35%) starting from readily available phloroglucinol and 4-hydroxy- or 4-methoxybenzaldehyde. Preliminary results indicate that some of these compounds have an interesting activity against S. aureus. binaringenin - biapigenin - protecting groups - antibacterial activity
The synthesis of some natural and synthetic biflavonoids was performed in good overall yields starting from readily available materials via high yielding aldol and Ullmann condensations. Some of these compounds, especially bichalcones, display an interesting activity against fungi, higher than that of the corresponding monomers. (C) 2011 Elsevier Ltd. All rights reserved.

Two compounds of a new class of antibiotics, hazimycinfactors5 and 6, which are interconvertible in a base-catalysed process, are each shown to be di-tyrosine analogues containing two isonitrile groups; their synthesis by two routes, one of which involves oxidative coupling of N-formyl-L-typrosine methyl ester with horse-radish peroxidase, is described.
