The addition of allyltrimethylsilane to cyclic N-acyliminium ions derived from (S)-(+)-mandelic acid and cyclohexyl-based chiral auxiliaries
(Soc Brasileira QuimicaSao PauloBrasil, 2001)
Chiral auxiliary-mediated enantioenrichment of (±)-ibuprofen, under steglich conditions, with secondary alcohols derived from (R)-carvone
(Sociedade Brasileira de Química, 2010-03)
The synthesis of a series of chiral secondary alcohols derived from (R)-carvone, and the stereochemical outcome of their reaction with (±)-ibuprofen, is reported. The racemic drug was transformed into the corresponding ...
Diastereofacial selectivity in ketene [2+2] cycloaddition to endocyclic enecarbamates bearing a chiral auxiliary. Synthesis of the (-)-Geissman-Waiss lactone

A chiral auxiliary derived from levoglucosenone in assymetric Diels-Alder transformations
(Pergamon-Elsevier Science Ltd, 2005-10-10)
The Diels-Alder reaction of the acrylate derived from levoglucosenone with cyclopentadiene was studied under several conditions, in the presence and absence of a Lewis acid. The results showed satisfactory diastereomeric ...

Asymmetric construction of substituted pyrrolidines via 1,3-dipolar cycloaddition of azomethine ylides and chiral acrylates derived from biomass
(ElsevierAmsterdam, 2014-04)
The first application of chiral auxiliaries synthesized from levoglucosenone (a biomass-derived anhydrosugar) in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides is herein reported. The corresponding ...
Palladium asymmetric reduction of beta-carboline imines mediated by chiral auxiliaries assisted by microwave irradiation
