A novel intramolecular Ugi reaction with 7-azabicyclo[2.2.1]heptane derivatives followed by post-condensation acylations: a new entry to azanorbornyl peptidomimetics.

چکیده
beta-amino acids have been employed in the past as bifunctional building blocks in intramolecular Ugi multicomponent reactions to yield beta-lactam derivatives. By using 7-azabicyclo[2.2.1]heptane-2-carboxylic acid, a different outcome has been observed and rationalised. The final compounds are polyfunctionalised azabicyclic peptidomimetics, and further elaboration can be achieved exploiting an additional carboxylic group that is not involved in the multicomponent step.

An unexpected formation of the novel 7-oxa-2-azabicyclo[2.2.1]hept-5-ene skeleton during the reaction of furfurylamine with maleimides and their bioprospection using a zebrafish embryo model.
An unexpected intramolecular cyclization during the reaction of furfurylamine with maleimides is reported as a novel strategy for the efficient green synthesis of the 7-oxa-2-azabicyclo[2.2.1]hept-5-ene skeleton. Under the same reaction conditions, 7-oxabicyclo[2.2.1]hept-5-enes were synthesized when furfurylamine was N-protected by the acetyl group. Both types of bicycloheptenes were screened ...

The stoichiometric reaction of para-methoxyanilines and B(C6F5)3 under H2 results in reduction of the N-bound phenyl ring(s), and subsequent transannular ring closure with elimination of methanol, affording the respective 7-azabicyclo[2.2.1]heptane derivatives.

An efficient Ugi three-component reaction of a preformed chiral ketimine derived from isatin with various isonitrile and acid components has been developed. The reactions proceeded smoothly and in a stereocontrolled manner with regard to the new center of the Ugi products due to the stereoinduction of the amine chiral residue. A wide variety of novel chiral 3,3-disubstituted 3-aminooxindoles we...
متن کاملA Novel Strategy of Ugi-4CR/Huisgen 1,3-Dipolar Synthesis of 1H-1,2,3-Triazole-Modified Peptidoimetics
In this protocol, we report a novel approach for the synthesis of a new class of heterocyclic 1H-1,2,3-triazole-modified peptidomimetic compounds. The process consists of an Ugi four-component condensation reaction of amines, an isocyanide, an aldehyde and acids followed by a Huisgen 1,3-dipolar cycloaddition reaction with an azide group in the presence of a catalytic amount of CuSO4</...
متن کاملSynthesis of acylhydrazino-peptomers, a new class of peptidomimetics, by consecutive Ugi and hydrazino-Ugi reactions
Herein we describe a versatile approach for the synthesis of acylhydrazino-peptomers, a new class of peptidomimetics. The key idea in this approach is based on a simple route using a one-pot hydrazino-Ugi four-component reaction followed by a hydrazinolysis or hydrolysis reaction and subsequent hydrazino-Ugi reaction or classical Ugi reaction for the construction of acyclic acylhydrazino-peptom...
