[4] A search using SciFinder, on the other hand, gives just 3 hits when inquiring for "chiral 1,3-diamines": a ferrocene derivative, [5] a class of anilines [6] useful as a chiral proton source, and some diaminopropanes derived from chiral aziridines. [7] Chiral diamines have gained considerable importance in pharmaceutical chemistry, mostly 1,2-diamines, as in the synthesis of tamiflu; [8a,8b] in addition, examples of 1,3-diamines of pharmaceutical importance are known.…”
