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.

Ammoniomethyl trifluoroborates are very powerful reagents that can be used to access biologically relevant aryl‐ and heteroaryl‐methylamine motifs via Suzuki–Miyaura cross‐couplings. Until now, this method was limited to the production of tertiary and primary amines. The synthesis of a large array of secondary ammoniomethyltrifluoroborates has been achieved through a one step nucleophilic substitution

contemporary organic synthesis relies on transformations that are driven by the intrinsic, so‐called “natural”, polarity of chemical bonds and reactive centers. The design of unconventionally polarized synthons is a highly desirable strategy, as it generally enables unprecedented retrosynthetic disconnections for the synthesis of complex substances. Whereas the umpolung of carbonyl centers is a well‐known

Disclosed are specific aminoalkyl naphthalenediol derivatives that enhance natural human host resistance to viral infectious organisms and particularly AIDS-related viruses. Such agents are also administered prophylactically to individuals whose resistance to infection has been specifically immunocompromised by an AIDS-related (HIV) virus.

A chemoselective intramolecular Buchner reaction employing iodoniumylides as safe carbene precursors has been developed. Iodoniumylides are generated in situ from N-benzyl-2-cyanoacetamides and PhI(OAc)2 in the presence of base and undergo intramolecular Buchner reaction under catalysis from Cu(OAc)2·H2O, affording fused cyclohepta-1,3,5-triene derivatives in up to 85% yield. The N,N-dibenzyl-2-cyanoacetamides

NaH2PO2 was found to promote reductive amination. Being nontoxic, stable, environmentally benign, and available in bulk amounts, this reducing agent showed a powerful potential to compete with classical reductants applied in the target process. An E factor of 1 was achieved for the substrate scope. Different carbonyl compounds reacted with amines under the developed conditions. The reaction demonstrated
