Superacid-promoted synthesis of quinoline derivatives
Klumpp, Douglas A.,Stentzel, Michael R.,Vuong, Hein
, (2020)
A series of vinylogous imines have been prepared from anilines and cinnamaldehydes. These substrates react in superacidic media to provide quinolines and related compounds. A mechanism for the conversion is proposed which involves the cyclization of dicationic superelectrophilic intermediates. Aromatization of the quinoline ring is thought to occur by superacid-promoted elimination of benzene.

The direct insertion of nitriles into zirconocene-1-aza-1,3-diene complexes provides an efficient, chemoselective, and controllable synthesis of N-H and N-substituted pyrroles upon acidic aqueous work-up. The outcome of the reaction (that is, the formatio
Synthesis of 4-phosphono-β-lactams via phosphite addition to acyliminium salts
Stevens, Christian V.,Vekemans, Wannes,Moonen, Kristof,Rammeloo, Thomas

4-Aryl-4-phosphono-β-lactams are prepared by acylation of iminium salts with chloroacetyl chloride followed by phosphite addition and ring closure using sodium hydride as a base. Deacylation of the iminium salt is in competition with the desired addition of phosphites to acyliminium salts, which lowers the yield of the reaction.
Synthesis and Structure-Activity Relationships of Naftifine-Related Allylamine Antimycotics

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.
