Ruthenium-catalyzed selective N ,N-diallylation- and N ,N ,O-triallylation of free amino acids.
Selective N ,N-diallylation and N ,N, O-triallylation of free amino acids in the presence of catalytic amounts of RuCp*(MeCN)(3)PF(6) is reported. The crucial influence of the solvent makes these allylation reactions selectively possible.
متن کامل[3 + 2]-Annulations of N-alkyl-3-substituted indoles with quinone monoketals catalysed by Brønsted acids.
An organocatalytic dearomative [3 + 2]-annulation of N-alkyl-3-alkylindoles with quinone monoketals is developed. The reaction provides a mild and straightforward way to various benzofuro[2,3-b]indolines of potential biological and pharmaceutical interest in moderate to good yields. Moreover, when 3-phenylindole, a problematic substrate in previous relevant studies, was used as the substrate un...
متن کاملThe proteomics of N-terminal methionine cleavage.
Methionine aminopeptidase (MAP) is a ubiquitous, essential enzyme involved in protein N-terminal methionine excision. According to the generally accepted cleavage rules for MAP, this enzyme cleaves all proteins with small side chains on the residue in the second position (P1'), but many exceptions are known. The substrate specificity of Escherichia coli MAP1 was studied in vitro with a large (>...
متن کامل2-Amino-N,3-dimethylbenzamide
In the title compound, C9H12N2O, the mean plane through the amide group and the benzene ring form a dihedral angle of 33.93 (7)°. An intra-molecular N-H⋯O hydrogen bond is present. In the crystal, mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, forming double-stranded chains parallel to the b axis.
متن کاملSynthesis of Substituted 2-Amino-1,3-oxazoles via Copper-Catalyzed Oxidative Cyclization of Enamines and N,N-Dialkyl Formamides.
A facile synthesis of 2-amino-1,3-oxazoles via CuI -catalyzed oxidative cyclization of enamines and N,N-dialkyl formamides has been developed. The reaction proceeds through an oxidative C-N bond formation, followed by an intramolecular C(sp2 )-H bond functionalization/C-O cyclization in one pot. This protocol provides direct access to useful 2-amino-1,3-oxazoles and features protecting-group-fr...
