Chemoselectivity and stereoselectivity of cyclisation pathways leading to bicyclic tetramates controlled by ring-chain tautomerisation in thiazolidines.

Organic & biomolecular chemistry

Panduwawala TD, Iqbal S, Tirfoin R, Moloney MG.
PMID: 27089842
Org Biomol Chem. 2016 May 11;14(19):4464-78. doi: 10.1039/c6ob00557h.

Chemoselective Dieckmann cyclisation reactions on N-malonyl thiazolidine templates derived from cysteine and pivaldehyde or aromatic aldehydes may be used to access bicyclic tetramates, for which different pathways operate as a result of differing ring-chain tautomeric behaviour of the respective...

The internal structure of nucleons (protons and neutrons) remains one of the greatest outstanding problems in modern nuclear physics. By scattering high-energy electrons off a proton we are able to resolve its fundamental constituents and probe their momenta and...

Colonoscopy without sedation: Patient factors alone are less likely to influence its uptake.

Endoscopy international open

Iqbal N, Ramcharan S, Doughan S, Shaikh I.
PMID: 27227110
Endosc Int Open. 2016 May;4(5):E534-7. doi: 10.1055/s-0042-102877. Epub 2016 May 03.

BACKGROUND AND STUDY AIMS: Conscious sedation during colonoscopy minimizes discomfort, improves polyp detection rates, and reduces technical failure, but carries medication-related risks and requires dedicated and costly recovery services. Sedation-free procedures may offer a safer alternative. We aimed to...
