Catalytic Nucleophilic Glyoxylation of Aldehydes

open access: yes, 2016
β-Silyloxy-α-keto esters are prepared through a cyanide-catalyzed benzoin-type reaction with silyl glyoxylates and aldehydes. The products undergo a dynamic kinetic resolution to provide enantioenriched orthogonally protected alcohols and can be ...

Lewis acid-promoted carbonyl addition of 1,3-bis(silyl)propenes

open access: yes, 2008
A novel synthetic protocol for Lewis acid-promoted addition of 1,3-bis(silyl)propenes to N-phenyl glyoxylamide and ethyl glyoxylate is developed.

New cyclohexyl-based chiral auxiliaries: enantioselective synthesis of α-hydroxy acids

open access: yes, 1995
(1R,2R)-2-(4-tert-Butylphenoxy)cyclohexan-1-ol (5) and (1R,2R)-2-(4-phenylphenoxy)cyclohexan-1-ol (6) have been used for the first time as chiral auxiliaries.

Stereoselective synthesis of optically active 2-hydroxymandelic acids and esters via Friedel - Crafts coordinated reaction: Crystal structure of chiral dichloro[2-(1-oxido-1-menthoxy-carbonylmethyl)-4-methoxyphenoxido- O,O,O]titanium

open access: yes, 1999
Highly diastereoselective hydroxyalkylation of phenols with chiral glyoxylates was performed. Hydrolysis or reduction of the esters 3 afforded 2-hydroxymandelic acids 6 and diols 5 in high yields and enantiomeric pure form.

Highly Enantioselective Synthesis of 2-Furanyl-hydroxyacetates from Furans via the Friedel−Crafts Reaction

open access: yes, 2016
The Friedel−Crafts reaction of alkyl glyoxylates with variously substituted furans was found to be efficiently catalyzed under simple, undemanding conditions by a 6,6′-dibromo-BINOL/Ti(IV) complex with high enantioselectivity.

Highly diastereoselective synthesis of aza-diels-alder reaction of danishefsky diene wiht glyoxylate imines [PDF]

open access: yes, 2012
Aza-Diels-Alder reaction is an exceptionally powerful synthetic method for the construction of six-membered nitrogen-heterocycles.[1-3] The reaction of Danishefsky's diene 1 with iminoacetates 2 (imines of glyoxylates) provides a convenient protocol for ...
