Enantioselective asymmetric alkylation of achiral lithium enolates mediated by chiral tetradentate amine ligands is achieved to give chiral quaternary carbon centers. Turnover of a chiral tetradentate amine in the presence of an achiral bidentate amine during the reaction is also realized.
Thione photochemistry: Abstraction and cyclization at the β-position of aralkyl thiones from two excited states
Couture, Axel,Gomez, Jose,De Mayo, Paul
, p. 2010 - 2016 (2007/10/02)
Excitation of a series of β-substituted aralkyl thiones either to the S2 (π,π*) state or to the S1 (n,π*) state leads to a formal insertion into the β-position and the formation of cyclopropyl thiols. The mechanisms of intramolecular
