We report the preparation of a range of N-protected amino acid derived guanidine organocatalysts and their application to the Michael addition of 2-hydroxy-1,4-napthoquinone to β-nitrostyrene, achieving a maximum ee of 26%. Whilst these catalysts gave poo

An operationally simple, and cost efficient conversion of carboxylic acids into hydroxamic acid derivatives via a high-energy mechanochemical activation is presented. This ball milling methodology was applied to a wide variety of carboxylic acids dramatically improving purification issues associated with this class of molecules, which still remain one of the main bottlenecks of classical methodologies. (Figure presented.).
A rapid and efficient one-pot method for the reduction of N-protected α-amino acids to chiral α-amino aldehydes using CDI/DIBAL-H

N-Protected amino acids can be easily converted into chiral α-amino aldehydes in a one-pot reaction by activation with CDI followed by reduction with DIBAL-H. This method delivers Boc-, Cbz- and Fmoc-protected amino aldehydes from proteinogenic amino acids in very good isolated yields and complete stereointegrity.
Carbonyldiimidazole (CDI) mediated synthesis of Nα- protected amino acid azides: Application to the one-pot preparation of ureidopeptides
Vasantha,Vishwanatha,Sureshbabu, Vommina V.
experimental part, p. 1093 - 1098 (2012/06/01)
Synthesis of Nα-protected amino acyl azides starting from corresponding acids via the carbonyldiimidazole (CDI) activation is described. The protocol is extended for a one-pot preparation of ureido peptides that circumvents the isolation of acy
Size control and compartmentalization in self-assembled nano-structures of a multisegment amphiphile
Boekhoven, Job,Van Rijn, Patrick,Brizard, Aurelie M.,Stuart, Marc C. A.,Van Esch, Jan H.
supporting information; experimental part, p. 3490 - 3492 (2010/07/16)
A "multisegment amphiphile" has been synthesized by covalently connecting two well known building blocks, a gelator and a micelle forming surfactant. Self-assembly results in the formation of compartmentalized nano-object displaying properties inherited f
Decarboxylative Carbon Acylation of Malonates with Aminoacylimidazoles Mediated by Lewis Acids
Mansour, Tarek S.,Evans, Colleen A.
, p. 773 - 781 (2007/10/02)
Various N-protected aminoacylimidazoles undergo decarboxylative carbon acylation with sodium or potassium monomethylmalonate in THF in the presence of MgCl2, CoCl2 or MnCl2 to give dipeptide analogues (3) in 45-82percent isolated yield.Amino ketoester (3e) undergoes intramolecular cyclization induced by diisopropylethylamine and anhydrous magnesium chloride to trisubstituted tetramic acid (4).
