Enantioselective Synthesis of Isoindolines: An Organocatalyzed Domino Process Based On the aza-Morita-Baylis-Hillman Reaction**
TL;DR: The organocatalytic asymmetric domino process is a very attractive method because of its ability to construct complexchiral molecules from readily available substrates under mild reaction conditions in two or more steps in a single operation.
Journal ArticleDOI
PdII/PdIV Catalytic Enantioselective Synthesis of Bicyclo[3.1.0]hexanes via Oxidative Cyclization of Enynes
TL;DR: The first asymmetric Pd(II)/Pd(IV) catalysis has been achieved by employing the combination of a hypervalent iodine reagent and a chiral ligand, SPRIX.
Journal ArticleDOI
Phosphine-Catalyzed β,γ-Umpolung Domino Reaction of Allenic Esters: Facile Synthesis of Tetrahydrobenzofuranones Bearing a Chiral Tetrasubstituted Stereogenic Carbon Center
Shinobu Takizawa,Kenta Kishi,Yasushi Yoshida,Steffen Mader,Fernando Arteaga Arteaga,Shoukou Lee,Manabu Hoshino,Magnus Rueping,Makoto Fujita,Hiroaki Sasai +9 more
TL;DR: The designed sequence, involving oxy-Michael and Rauhut-Currier reactions, produced highly functionalized tetrahydrobenzofuranones, bearing a chiral tetrasubstituted stereogenic center, in up to 96 % ee.
Journal ArticleDOI
Dinuclear chiral vanadium catalysts for oxidative coupling of 2-naphthols via a dual activation mechanism.
TL;DR: Dinuclear vanadium(v) complexes (R(a),S,S)- and show considerably higher catalytic activity than previously reported vanadium complexes for the oxidative coupling of 2-naphthols.
Journal ArticleDOI
Dual activation in a homolytic coupling reaction promoted by an enantioselective dinuclear vanadium(IV) catalyst
Hidenori Somei,Yasuaki Asano,Tomokazu Yoshida,Shinobu Takizawa,Hiroshi Yamataka,Hiroaki Sasai +5 more
TL;DR: In this article, a new concept of dual activation catalysis in homolytic coupling reaction of 2-naphthol derivatives is described, and the dinuclear vanadium(IV) catalyst (R, S, S, S )-1a promotes the oxidative coupling reaction.
