, p. 1359 - 1364 (2002)
Efficient methods for the synthesis of chiral n,n+1-diamino acids starting from L-glutamic acid were developed. A second generation prototype amino acid based dendrimer, containing 1,3-propanediamine as the core and 4,5-diaminopentanoic acid as the branching unit, was synthesised following the divergent approach. Diaminobutane poly(propyleneimine) dendrimers modified at the periphery with n,n+1-diamino acids were synthesized and characterized.
Synthesis of 5-amino- and 4-hydroxy-2-phenylsulfonylmethylpiperidines
Masse, Julien,Langlois, Nicole
experimental part, p. 417 - 432 (2009/09/06)
Suitable protected 5-amino- and 4-hydroxy-2-phenylsulfonylmethylpiperidines were synthesized from functionalized N-benzyloxycarbonylpiperidin-l-ones through the opening of lactam ring by methyl phenyl sulfone carbanion followed by reductive aminocyclization.
Diastereoselective synthesis of enantiopure differentially protected cis-4,5-diaminopiperidin-2-one through intramolecular transamidation
Langlois, Nicole
, p. 9531 - 9533 (2007/10/03)
The diastereoselective synthesis of enantiopure differentially protected cis-4,5-diaminopiperidin-2-one was achieved by means of conjugate addition of ammonia to an unsaturated γ-lactam and transamidation reaction with ring expansion as the main steps.
