Construction of an asymmetric quaternary carbon via an asymmetric aza-Claisen rearrangement and its application in the total synthesis of (+)-α-cuparenone

Autor: Fumiaki Miyamae, Tetsuto Tsunoda, Mitsuyo Horikawa, Makoto Yoshizuka, Makoto Inai, Takeshi Nishii, Hiroto Kaku

Publikováno v: Tetrahedron: Asymmetry. 23:739-741

Excess lithium hexamethyldisilazide (LHMDS) with LiCl prompted the asymmetric aza-Claisen rearrangement of carboxamide and retarded the decomposition of its amide enolate. The addition of these two reagents was a key step that led to the total synthe

Intramolecular amidoalkylation of chiral imines and iminium ions: Stereoselective synthesis of anti-1,2- and -1,3-aminoalcohols

Autor: Rieko Kunitake, Shô Itô, Makoto Yoshizuka, Tatsuo Izawa, Hideaki Hioki

Publikováno v: Tetrahedron Letters. 36:2289-2292

When treated with Lewis acids, 2- or 3-vinyl- or -phenylsiloxyaminoacetals generated the corresponding imines or iminium ions which in turn underwent smooth intramolecular amidoalkylation to afford anti-1,2- or -1,3-aminoalcohol derivatives in very h
