Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The transient 1-azafulvenium methides 24, 26 and 28 generated by thermal extrusion of sulfur dioxide from pyrrolo[1,2-c][1,3]thiazole 2,2-dioxide 20 (R = Me), 22 and 23 undergo sigmatropic [1,8]H shifts and the 1-acyl derivatives 30 electrocyclise to give novel pyrrolo[1,2-c][1,3]oxazines 32. The analogous 1,2-diazafulvenium methide 36 has been intercepted in [8 + 2] cycloadditions with electron-rich silylated acetylenes to give adducts 37-40. This behaviour is partially explained by Frontier MO theory.
