Ketone α-alkylation at the more-hindered site
Nature Communications, 2023 Control of the regioselectivity of α-alkylation of carbonyl compounds is a longstanding topic of research in organic chemistry. By using stoichiometric bulky strong bases and carefully adjusting the reaction conditions, selective alkylation of ...

Copper(I)-catalyzed asymmetric alkylation of α-imino-esters
Nature Communications, 2023 Asymmetric alkylation of enolates is one of the most direct and important reactions to prepare α-chiral carbonyl compounds. Except for the classical methods that rely on the use of chiral auxiliaries, asymmetric catalysis emerged as a powerful tool ...

Regioselective Alkylation of an Oxonaphthalene-Annelated Pyrrol System
Molbank, 2009 The regioselective alkylation of an oxonaphthalene-annelated pyrrole system is reported. The regioselectivity of alkylation can be controlled by the selection of the solvent.
