Investigation of macrocyclisation routes to 1,4,7-triazacyclononanes : efficient syntheses from 1,2-ditosylamides [PDF]

, 2008
Two routes to the synthesis of a cyclohexyl-fused 1,4,7-triazacyclononane involving macrocyclisations of tosamides have been investigated. In the first approach, using a classic Richman-Atkins-type cyclisation of a cyclohexyl-substituted 1,4,7 ...

Poly(ethylene Glycol)‐Based Peptidomimetics (Pegtides) of Antimicrobial Peptides

ChemBioChem, EarlyView.
Polyethylene glycol (PEG) is commonly used to improve the pharmacokinetics and pharmacodynamics of therapeutic candidates by conjugation. Here PEG is exploited for peptidomimetic conversion of antimicrobial peptides (AMPs), as candidate antibacterial agents, by replacing their polyamide backbone. The pegtides obtained thereby can be readily synthesized

Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline

ChemistryEurope, EarlyView.
An indole synthesis via an allenyl ester intermediate at ambient temperature has been developed. The mild reaction conditions allow the use of a broad range of substrates. Notably, the utility of this approach is demonstrated through the asymmetric total synthesis of geissoschizoline, a Strychnos‐type monoterpenoid indole alkaloid.
