Abstract: Abstract The synthesis of novel of 4,5,6,7-tetrahydrobenzoxazol-2-ones is herein reported. They were obtained in moderate to good yields by a highly regio- and stereoselective Diels-Alder cycloaddition of N-substituted exo-oxazolidin-2-one dienes with chalcones or bis-chalcones as… read more here.

DOI: 10.1039/c7qo00290d
Abstract: We introduce Li+ involving cycloadditions between acetylene and ring-like cycloparaphenylenes (CPPs) in theory. Orbital analysis suggests an inverse electron-demand mechanism in which the diene CPP acts as an electron acceptor. Partial electron transfer to Li+… read more here.
