متن کاملDiastereo- and enantioselective conjugate addition of α-substituted nitroacetates to maleimides under base-free neutral phase-transfer conditions.
Highly diastereo- and enantioselective conjugate addition of α-substituted nitroacetates to maleimides under base-free neutral phase-transfer conditions was developed for the synthesis of α,α-disubstituted α-amino acid derivatives.
متن کاملChemical modification of lactose repressor protein using N-substituted maleimides.
Lactose repressor protein has been modified with N-ethylmaleimide, two N-maleimide spin labels, and an N-maleimide fluorophore. The reaction with repressor cysteine residues has been characterized. Approximately 2 of the 3 eq of cysteine/repressor monomer are reactive toward these reagents. Repressor cysteines are reactive toward these reagents in the order cysteine 140 greater than or equal to...
متن کاملCovalent attachment of antagonists to the α7 nicotinic acetylcholine receptor: synthesis and reactivity of substituted maleimides.
The 3-methylmaleimide congeners of the natural product methyllycaconitine (MLA) and an analogue covalently attach to functional cysteine mutants of the α7 nicotinic acetylcholine receptor (nAChR).
متن کاملEnantioselective synthesis of highly substituted furans by a copper(II)-catalyzed cycloisomerization-indole addition reaction.
A catalytic enantioselective reaction based on a copper(II) catalyst strictly containing chiral anionic ligands is described. In the present work, copper(II)-phosphate catalyst promotes the intramolecular heterocyclization of 2-(1-alkynyl)-2-alkene-1-ones and facilitates high levels of enantioselectivity in the subsequent nucleophile attack. Mechanistic studies suggest that formation of a coppe...
