Alternative Procedures for the Macrolactamisation of ω-Azido Acids
Bosch, Imma,Romea, Pedro,Urpi, Felix,Vilarrasa, Jaume
, p. 4671 - 4674 (2007/10/02)
ω-Azido acids, after activation of the carboxyl groups as mixed anhydrides, N3(CH2)nCOOCOAr (Ar = 3,5-dinitrophenyl or 2,4,6-trichlorophenyl), can be converted to macrolactams in good yields by treatment with Bu3P under high-dilution conditions; the prese
Activation of Dithiocarbamate by 2-Halothiazolium Salts
Sugimoto, Hirohiko,Makino, Itsuo,Hirai, Kentaro
, p. 2263 - 2267 (2007/10/02)
Activation of dithiocarbamate salts with 2-halo-3-alkyl-4-phenylthiazolium salt and subsequent one-pot nucleophilic reaction with N, S, and O nucleophiles provided substituted thioureas, dithiocarbamates, and thiocarbamates or amides, respectively, under very mild conditions.A useful thiocarbonyl-transfer reaction is also described that consists of activation of imidazolodithiocarbamate and a subsequent one-pot nucleophilic reaction. (Thiocarbonyl)diimidazole is generated in situ.
SYNTHESIS OF MESOIONIC TRIAZOLOPYRIDINE. III. APPLICATIONS OF N-ACYL MESOIONIC TRIAZOLOPYRIDINES AS ACYLATING REAGENTS.
Saito,Shimizu
, p. 2974 - 2980 (2007/10/02)
Utility of N-acyl mesoionic triazolopyridines as acylating reagents was investigated concerning with peptide synthesis. Several dipeptides and N-alkoxycarbonyl amino acids were prepared by use of these reagents.
