Development of a Strategy for the Asymmetric Synthesis of Polycyclic Polyprenylated Acylphloroglucinols via N-Amino Cyclic Carbamate Hydrazones: Application to the Total Synthesis of (+)-Clusianone Garnsey, Michelle R; Lim, Daniel; Yost, Julianne M; Coltart, Don M (2010)A broadly applicable asymmetric synthetic strategy utilizing N-amino cyclic carbamate alkylation that provides access to the various stereochemical permutations of a common structural motif found in many polycyclic polyprenylated ...
Direct Carbon-Carbon Bond Formation via Soft Enolization: A Biomimetic Asymmetric Mannich Reaction of Phenylacetate Thioesters Kohler, Mark C; Yost, Julianne M; Garnsey, Michelle R; Coltart, Don M (2010)An asymmetric Mannich reaction of phenylacetate thioesters and sulfonylimines using cinchona alkaloid-based amino (thio)urea catalysts is reported that employs proximity-assisted soft enolization. This approach to enolization ...
Direct carbon-carbon bond formation via soft enolization: aldol addition of alpha-halogenated thioesters Yost, Julianne M; Alfie, Rachel J; Tarsis, Emily M; Chong, Insun; Coltart, Don M (2011)alpha-Halo thioesters undergo soft enolization and syn-selective direct aldol addition to aldehydes in the presence of MgBr2 center dot OEt2 and i-Pr2NEt to produce alpha-halo-beta-hydroxy thioesters.
