Chiral donor−acceptor azetines as powerful reactants for synthesis of amino acid derivatives
(Nature Communications;, 2019-11-22)
Coupling reactions of amines and alcohols are of central importance for applications in chemistry and biology. These transformations typically involve the use of a reagent, activated as an electrophile, onto which nucleophile ...
Highly selective acylation of polyamines and aminoglycosides by 5-acyl-5-phenyl-1,5-dihydro-4H-pyrazol-4-ones
(Chemical Science;, 2017-08-30)
5-Acyl-5-phenyl-1,5-dihydro-4H-pyrazol-4-ones, accessible from arylpropargyl phenyldiazoacetates, are highly selective acyl transfer reagents for di- and polyamines, as well as aminoalcohols and aminothiols. As reagents ...
Formal [4+4]-, [4+3]-, and [4+2]-Cycloaddition Reactions of Donor-Acceptor Cyclobutenes, Cyclopropenes and Siloxyalkynes Induced by Brønsted Acid Catalysis
(Chemical Science;, 2021-02-18)
Brønsted acid catalyzed formal [4 + 4]-, [4 + 3]-, and [4 + 2]-cycloadditions of donor–acceptor cyclobutenes, cyclopropenes, and siloxyalkynes with benzopyrylium ions are reported. [4 + 2]-cyclization/deMayo-type ring-extension ...
