The selective N-monoderivatization of propane-1,3-diamine (5) with carbonyl and sulfonyl chlorides via2-phenylhexahydropyrimidine (6) was compared with the direct statisticmonoderivatization. It was found that, under optimized conditions, both methods are competitive to one another, depending, however, strongly on the reactivity of the eleclrophile used. The ‘hexahydropyrimidinemethod’ is more reliable
Solid-phase synthesis and antibacterial activity of hydroxycinnamic acid amides and analogues against methicillin-resistant Staphylococcus aureus and vancomycin-resistant S. aureus
A library of hydroxycinnamic acid amides (HCAAs) and analogues were synthesized using solid-phase synthesis technique. These compounds were screened for antibacterial against methicillin-resistant Staphylococcus aureus (MRSA) (11 strains) and vancomycin-resistant S. aureus (VRSA) (4 strains). Dihydrocaffeoyl analogues showed activity against VRSA which were better than the reference drugs, vancomycin and oxacillin. These compounds also exhibited antibacterial activity against MRSA, which were more potent than oxacillin. (c) 2006 Elsevier Ltd. All rights reserved.
