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.
Allylicalcohols and allylic amines were directly utilized in a Pd-catalyzed hydrogen-bond-activated allylic amination under mild reaction conditions in the absence of any additives. The cooperative action of a Pd-catalyst and a hydrogen-bonding solvent is most likely responsible for its high reactivity. The catalytic system is compatible with a variety of functional groups and can be used to prepare
