- Synthesis of a naturally occurring diene-containing amino acid and its glutamyl dipeptide via N-acyliminium ion chemistry
-
The syntheses of the naturally occurring unusual unsaturated amino acid (S)-2-amino-3-methylene-4-pentenoic acid and the corresponding γ-glutamyl dipeptide are described. Key steps are an N-acyliminium ion addition using allenylmethylsilane as nucleophile and an enzymatic resolution mediated by the L-aminopeptidase from Pseudomonas putida. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

- A photocaged, cyclopropene-containing analog of the amino acid neurotransmitter glutamate
-
Substituted cyclopropenes serve as compact biorthogonal appendages that enable analysis of biomolecules in complex systems. Neurotransmitters, a chemically diverse group of biomolecules that control neuron excitation and inhibition, are not among the systems that have been studied using biorthogonal chemistry. Here we describe the synthesis of cyclopropene-containing analogs of the excitatory amino acid neurotransmitter glutamate starting from a Garner's aldehyde-derived alkyne. The deprotected cyclopropene glutamate was stable in solution but decomposed upon concentration. Appending a light-cleavable group improved the stability of the cyclopropene while simultaneously caging the neurotransmitter. This strategy has the potential to permit deployment of cyclopropene-modified glutamate as a bioorthogonal probe of the neurotransmitter glutamate in vivo with spatiotemporal precision.

- Stereoselective Bromination of Dehydroamino Acids with Controllable Retention or Inversion of Olefin Configuration
-
Dehydroamino acids react with brominating reagents to produce syn-α-bromo imines as the major products, which undergo tautomerization to mixtures of the diastereomeric (E)- and (Z)-β-bromo-α,β-dehydroamino acids upon treatment with base.Herein, we examine
