Highly diastereoselective self-assembly of chiral tris(m-ureidobenzyl)amino capsules.
نویسندگان
چکیده
The self-assembly of chiral tris(m-ureidobenzyl)amines to give dimeric capsules is a highly diastereoselective process in solution, while in the solid state, the formation of the corresponding capsules is not only diastereoselective but also regioselective.

Novel capsular aggregates from flexible tripodal triureas with C(s) symmetry.
Tris(2- and 3-ureidobenzyl)amines with C(s) symmetry self-assemble in solution forming mixtures of regioisomeric capsular aggregates, one of which is chiral and the other centrosymmetric. Under certain conditions, a predominance of the centrosymmetric regioisomer is found before equilibrium, that is, a mixture close to the statistical ratio of the two species is reached. In the solid state, th...

Molecular capsules composed of amino acid or peptide derivatives connected to resorcin[4]arene scaffolds through acylhydrazone linkers have been synthesized using dynamic covalent chemistry (DCC) and hydrogen-bond-based self-assembly. The dynamic character of the linkers and the preference of the peptides towards self-assembly into β-barrel-type motifs lead to the spontaneous amplification of f...

Highly diastereoselective aldol additions of (2R,4S)-3-tert-butyl 4-methyl 2-tert-butyloxazolidine-3,4-dicarboxylate (1) are reported. The utility of the highly substituted oxazolidines of type 1 for diastereoselective a-addition of the fully protected amino acid L-serine with achiral and chiral carbonyl compounds is demonstrated and the relative and absolute configuration of the aldol products...
