Results suggest that BODIPY-(GlcNAc)(2)-ClAc could be an in vivo inhibitor of cytoplasmic PNGase.
Trifluoromethylation reactions for the synthesis of β-trifluoromethylamines.
A multitalented system: N-migratory oxytrifluoromethylation and one-pot three-component reactions of allylamines as well as the aminotrifluoromethylation of alkenyl amines all proceeded efficiently…
A New Enantioselective Total Synthesis of AI-77-B
An enantioselective total synthesis of AI-77-B (1), a gastroprotective substance isolated from a culture broth of Bacillus pumilus AI-77, was performed in high overall yield. In this synthesis, the…
Catalytic Regio- and Enantioselective Proton Migration from Skipped Enynes to Allenes
Rapid Trifluoromethylation of Indole Derivatives
Cyclisation of bisphosphonate substituted enynes
A "catch-and-release" protocol for alkyne-tagged molecules based on a resin-bound cobalt complex for peptide enrichment in aqueous media.
Selective enrichment and detection of an amine derived from the "catch and release" of an alkyne-tagged dipeptide in the presence of various peptides has been accomplished under highly dilute conditions, as determined by mass spectrometry.

The results underscore the importance of the N-acetyl groups of chitobiose for PNGase recognition, and reactivity and position of the leaving group at the reducing end are also important factors.
A study of (binap)(enyne)tetracarbonyldicobalt(0) complexes.
Four (binap)(enyne)tetracarbonyldicobalt(0) complexes have been synthesised and their reactivity monitored by variable temperature NMR spectroscopy, and the structure of 12 was determined by X-ray crystallography, and its presence under Pauson-Khand reaction conditions was verified by NMRSpectroscopy.
A New Enantioselective Synthesis of the Aminodihydroisocoumarin Moiety of AI-77-B
The aminodihydroisocoumarin moiety of AI-77-B, a gastroprotective substance isolated from Bacillus pumilus AI-77, has been prepared from a convenient chiral synthon of L-erythrose by combination of…
