Highly Enantioselective Reduction of a Small Heterocyclic Ketone: Biocatalytic Reduction of Tetrahydrothiophene-3-one to the Corresponding (R)-Alcohol
Jack Liang,Emily Mundorff,Rama Voladri,Stephan Jenne,Lynne Gilson,Aaron Conway,Anke Krebber,Wong John Wing,Gjalt W. Huisman,Susan Jane Truesdell,James Lalonde +10 more
TL;DR: By leveraging enzyme evolution technologies, the enantioselectivity of a KetoREDuctase (KRED) towards the nearly spatially symmetrical ketone tetrahydrothiophene-3-one was increased from 63% ee to...

1.5 – The Aldol Reaction: Acid and General Base Catalysis
TL;DR: This chapter summarizes the aldol reaction from a historical perspective and points out the limitations of the reaction as it was generally used prior to about 15 years ago.
Reference EntryDOI
The Aldol Condensation
TL;DR: The aldol condensation as discussed by the authors is defined as the condensation of an aromatic aldehyde or ketone usually in the presence of a basic catalyst, and has been applied to many other condensations involving the reaction of an α-ketone or β-aldol.

Free radical ring-expansion leading to novel six- and seven-membered heterocycles
Paul Dowd,Soo-Chang Choi +1 more
TL;DR: In this article, free radical promoted ring expansion of nitrogen-, oxygen and sulfur-containing heterocyclic β-keto esters is described for phenylselenomethyl derivatives with tri-n-butyltin hydride leasds to smooth one-carbon ring expansion.
