In their 2012 report, the President's Council of Advisors on Science and Technology advocated "replacing standard science laboratory courses with discovery-based research courses"-a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences...

Enantioselective Extraction of Dinitrophenyl Amino Acids Mediated by Lipophilic Deoxyguanosine Derivatives: Chiral Discrimination by Self-Assembly.

Angewandte Chemie (International ed. in English)

Andrisano V, Gottarelli G, Masiero S, Heijne EH, Pieraccini S, Spada GP.
PMID: 10458795
Angew Chem Int Ed Engl. 1999 Aug;38(16):2386-2388. doi: 10.1002/(sici)1521-3773(19990816)38:16<2386::aid-anie2386>3.0.co;2-s.

The transfer of potassium salts of dinitrophenyl amino acids from water to chloroform by the lipophilic guanosine derivative 1 takes place enantioselectively. Depending on the K(+):1 ratio, G-quartets of 1 self-assemble into octamers (O) or polymers.

Synthesis of Secondary Amines via N-(Benzoyloxy)amines and Organoboranes.

The Journal of organic chemistry

Phanstiel O, Wang QX, Powell DH, Ospina MP, Leeson BA.
PMID: 11674150
J Org Chem. 1999 Feb 05;64(3):803-806. doi: 10.1021/jo981613l.

A variety of primary amines (R-NH(2)) were converted to their corresponding N-(benzoyloxy)amines (i.e., R-NHOCOPh) under biphasic conditions in excellent yields (63-90%). The intermediate N-(benzoyloxy)amines were converted to their N-ethylamine derivatives upon reaction with triethylborane in THF in good yield...

Doped nematic phases: a tool for amplifying and detecting chirality.

Enantiomer

Proni G, Spada GP.
PMID: 11570423
Enantiomer. 2001;6(2):171-9.

Doping nematic liquid crystals with non-racemic chiral compounds induces twisted nematics (cholesteric phases). This phenomenon allows the detection via spectroscopic or non-spectroscopic methods of chiral compounds through the detection (and eventually quantification) of the macroscopic induced cholesteric twist.

Internal energy deposition in chemical ionization/tandem mass spectrometry.

Journal of the American Society for Mass Spectrometry

Ospina MP, Powell DH, Yost RA.
PMID: 12586459
J Am Soc Mass Spectrom. 2003 Feb;14(2):102-9. doi: 10.1016/S1044-0305(02)00814-0.

The efficiency of the collision-induced dissociation (CID) process as a function of the internal energy deposited into the ion during the ionization event was evaluated. (M + H)+ ions of pyrrole, pyrrolidine, pyridine and piperidine (five and six-membered ring...

Conformational analysis in solution of C(2)-symmetric 1, 1'-binaphthyl derivatives by circular dichroism spectroscopy and cholesteric induction in nematic mesophases.

The Journal of organic chemistry

Proni G, Spada GP, Lustenberger P, Welti R, Diederich F.
PMID: 10970290
J Org Chem. 2000 Sep 08;65(18):5522-7. doi: 10.1021/jo0001683.

The twisting ability of a series of 1,1'-binaphthalene compounds used as dopants in nematic solvents has been related to the dihedral angle theta between the two naphthalene moieties. While in the case of the more flexible compounds the sign...

Classical decays in decoherent quantum maps.

García-Mata I, Saraceno M, Spina ME.
PMID: 12935077
Phys Rev Lett. 2003 Aug 08;91(6):064101. doi: 10.1103/PhysRevLett.91.064101. Epub 2003 Aug 05.

The linear entropy and the Loschmidt echo have proved to be of interest recently in the context of quantum information and of the quantum to classical transitions. We study the asymptotic long-time behavior of these quantities for open quantum...

Effect of strain on the photoisomerization and stability of a congested azobenzenophane: a combined experimental and computational study.

The journal of physical chemistry. A

Bassotti E, Carbone P, Credi A, Di Stefano M, Masiero S, Negri F, Orlandi G, Spada GP.

The stability and trans-cis photoisomerization properties of a macrocycle constituted of two para-aminoazobenzene units connected by two methylene bridges have been investigated by a combination of experimental and computational techniques. Irradiation at 365 nm leads to a photostationary state...

Chiral amplification in a cyanobiphenyl nematic liquid crystal doped with helicene-like derivatives.

Beilstein journal of organic chemistry

The addition of a chiral non-racemic dopant to a nematic liquid crystal (LC) has the effect of transferring the molecular chirality to the phase organization and a chiral nematic phase is formed. This molecular chirality amplification in the LC...

The chirality transfer in liquid crystals induced by two helical perylenequinones (namely, the natural compounds cercosporin and phleichrome) was investigated by integrating measurements of helical twisting power with a conformational analysis by DFT calculations and with the prediction of...
