Total synthesis of UCS1025A.

• Tristan H Lambert, Samuel J Danishefsky
• Journal of the American Chemical Society
• 2006

The enantioselective total synthesis of the telomerase inhibitor UCS1025A has been accomplished. The key transformation involves a remarkable boron Reformatsky coupling of iodolactone 13 and aldehyde… (More)

Enantioselective Brønsted base catalysis with chiral cyclopropenimines.

• Jeffrey S Bandar, Tristan H Lambert
• Journal of the American Chemical Society
• 2012

Cyclopropenimines are shown to be a highly effective new class of enantioselective Brønsted base catalysts. A chiral 2,3-bis(dialkylamino)cyclopropenimine catalyzes the rapid Michael reaction of a… (More)

The first example of aromatic cation-activated nucleophilic acyl substitution has been achieved. The conversion of carboxylic acids to their corresponding acid chlorides occurs rapidly in the… (More)

Multicatalytic synthesis of alpha-pyrrolidinyl ketones via a tandem palladium(II)/indium(III)-catalyzed aminochlorocarbonylation/Friedel-Crafts acylation reaction.

• Tim A Cernak, Tristan H Lambert
• Journal of the American Chemical Society
• 2009

An oxidative carbonylation reaction that generates acid chloride functionality has been developed. Furthermore, this aminochlorocarbonylation reaction has been merged with a catalytic Friedel-Crafts… (More)

An aromatic ion platform for enantioselective Brønsted acid catalysis

• Chirag D. Gheewala, Bridget E. Collins, Tristan H Lambert
• Science
• 2016

Chiral acid catalysts are useful for the synthesis of enantioenriched small molecules, but the standard catalysts require laborious and expensive preparations. Here, we describe a chiral Brønsted… (More)

Lanthanum(III) triflate-catalyzed cyclopropanation via intramolecular methylene transfer.

• David J Hardee, Tristan H Lambert
• Journal of the American Chemical Society
• 2009

A new method for cyclopropanation involving intramolecular methylene transfer from an epoxide to an olefin has been developed. This La(OTf)(3)-catalyzed process proceeds with good efficiency and with… (More)

Organocatalytic carbonyl-olefin metathesis.

• Allison K Griffith, Christine M Vanos, Tristan H Lambert
• Journal of the American Chemical Society
• 2012

The development of a catalytic carbonyl-olefin metathesis strategy is reported, in the context of the ring-opening metathesis of cyclopropenes with aldehydes using a simple hydrazine catalyst. The… (More)

Leaving group potential of a substituted cyclopentadienyl anion toward oxidative addition.

• Ethan L Fisher, Tristan H Lambert
• Organic letters
• 2009

The facility with which a substituted cyclopentadienyl anion may function as a leaving group for palladium-catalyzed allylation reactions is demonstrated. Reaction of several allylcyclopentadienyl… (More)
