Resistance to Macrocyclic Lactones

Current Pharmaceutical Biotechnology, 2012
Resistance to the macrocyclic lactones (MLs) has been confirmed or suspected in many target organisms and is a serious problem in some. For some species, such as parasitic nematodes of small ruminants, ML resistance has become severe enough to threaten effective worm control worm control.

Macrocyclic Polyethers and Their Complexes

Angewandte Chemie International Edition in English, 1972
AbstractThe most important, and almost unique, property of the macrocyclic polyethers (“crown compounds”) is their tendency to form complexes with alkali metal salts and salts with similar cations. Such complexes are held together by electrostatic attraction between the cation and the negative end of the CO dipoles.

Macrocyclic phosphazane ligands

Dalton Transactions, 2010
Inorganic macrocycles based on P(III)–N bonded frameworks can be obtained by a series of systematic routes, many of which parallel those commonly employed in the synthesis of more well known organic relatives. Such phosph(III)azane macrocycles exhibit a broad range of coordination behaviour, and provide new organically-soluble hosts, with unique steric

Polyphenyl Macrocyclic Oligophenylenes

Journal of the American Chemical Society, 2005
The Diels-Alder reaction of tribenzohexadehydro[12]annulene (12) and 3,4-diphenyl-2,5-dimethylcyclopentadienone (13) at 300 degrees C gave the triple adduct 2,3,10,11,18,19-hexaphenyl-1,4,9,12,17,20-hexamethylhexa-o-phenylene (6b) in 13% yield. NMR and X-ray analysis indicated that 6b adopts a screw conformation (C2) rather than a crown conformation ...

Multicomponent Syntheses of Macrocycles

2010
How to access efficiently the macrocyclic structure remained to be a challenging synthetic topic. Although many elegant approaches/reactions have been developed, construction of diverse collection of macrocycles is still elusive. This chapter summarized the recently emerged research area dealing with multicomponent synthesis of macrocycles, with ...
