- Polymethacrylic zinc porphyrin: A new approach to chiral recognition
-
A methacrylic homopolymer bearing in the side-chain achiral zinc tetraarylporphyrin moieties, has been studied as macromolecular chromophoric host to determine the absolute configuration of α,ω-diamines. The polymeric material resulted able to bind the ch

- β-PNA: Peptide nucleic acid (PNA) with a chiral center at the β-position of the PNA backbone
-
Peptide nucleic acid (PNA) monomers with a methyl group at the β-position have been synthesized. The modified monomers were incorporated into PNA oligomers using Fmoc chemistry for solid-phase synthesis. Thermal denaturation and circular dichroism (CD) studies have shown that PNA containing the S-form monomers was well suited to form a hybrid duplex with DNA, whose stability was comparable to that of unmodified PNA-DNA duplex, whereas PNA containing the R-form monomers was not.

- SYNTHESIS OF CHIRAL 1,2-DIAMINES
-
(1'S,5R,S)-(1'-phenyleth-1'-yl)-5-iodomethyl-imidazolines 4a, b have been synthesised and easily resolved by silica gel chromatography.The correlation between the configuration and the 1H-NMR chemical shifts allows to assign the configuration at the C-5 of these intermediates.Each pure diastereomer has been converted to R(-)- and to S(+)-1,2-propyldiamine, respectively.
