Synthesis and structure-activity relationships of naftifine-related allylamine antimycotics
摘要:
Naftifine (1) is the first representative of the new antifungal allylamine derivatives. Its biological activity is strictly bound to specific structural requirements that are unrelated to those of known antifungals. A tertiary allylamine function seems to be a prerequisite for activity against fungi. By systematic variation of the individual structural elements in 1, detailed structure-activity relationships are defined in which the phenyl ring is the structural feature permitting the widest variations. Versatile synthetic routes to allylamine derivatives and comparative biological data are presented.

carbene C,S palladium(II) π-allylcomplexes were successfully developed and characterized. Structural analyses of these complexes revealed that the organopalladium chelates adopt a skew-envelope conformation with a trans disposition of the substituents on the metal chelate rings. Utilizing these C,S palladium(II) π-allylcomplexes as catalysts, a catalytic system for the allylic amination reaction has
A new direct catalytic amination of allylic alcohols promoted by the combination of platinum and a large bite-angle ligand DPEphos was developed in which the allylic alcohol was effectively converted to a pi-allylplatinum intermediate without the use of an activating reagent. The use of the DPEphos ligand was essential for obtaining high catalyst activity and high monoallylation selectivity of primary
