Cu-Catalyzed O-alkylation of phenol derivatives with alkylsilyl peroxides.
TL;DR: A Cu-catalyzed O-alkylation of phenol derivatives using alkylsilyl peroxides as alkyl radical precursors is described and a mechanistic study suggested that the reaction proceeds via a radical mechanism.
Journal ArticleDOI
Design of an Axially Chiral DicarboxylicAcid and Its Application in Syntheses of Optically Active β-AminoAcids and β-Amino Phosphonic Acid Derivatives
Takuya Hashimoto,Keiji Maruoka +1 more
TL;DR: In this paper, an axially chiral dicarboxylic acid was developed as a new chiral Bronsted acid catalyst for N-Boc-protected p-amino acid derivatives.
Journal ArticleDOI
Complete Switch of Migratory Aptitude in Aluminum‐Catalyzed 1,2‐Rearrangement of Differently α,α‐Disubstituted α‐Siloxy Aldehydes
TL;DR: An enantioselective 1,2rearrangement of a,a-disubstituted a-siloxy aldehydes is developed by using the chiral aluminum Lewis acid 1 by identifying the crucial element governing the unique regioselectivity of this reaction, which would enable the selective preparation of any isomer at will.
Journal ArticleDOI
Remarkable catalytic activity of Me3Ga in the alkylation of hetero-substituted epoxides with alkynyllithiums
TL;DR: In this article, the region-and stereoselective ring-opening reaction of hetero-substituted epoxides with alkynyllithiums can be catalyzed by Me3Ga with remarkable efficiency at 0∼20 °C via pentacoordinate chelate-type complex.
Journal ArticleDOI
Iron‐Catalyzed Radical Cleavage/C–C Bond Formation of Acetal‐Derived Alkylsilyl Peroxides
TL;DR: Mechanistic studies suggest that the present reaction proceeds through a free-radical process involving carbon radicals generated by the homolytic cleavage of a carbon-carbon bond within the acetal moiety.
