The conformations of seven -(1-methoxycarbonylethyl)-Δ4-thiazoline-2-thiones with configuration of the chiral rotor have been studied by temperature-dependent NMR and CD spectroscopy, and for four compounds by molecularmechanicscalculations. The syn-anti equilibria previously reported have been confirmed, and other conformational processes, involving low energy barriers, have been shown to be operating
Some α-haloketones react with furan in methanolic solution in the presence of base to form the 3-oxo-8-oxabicyclo[3.2.1]oct-6-enes (), the products derived from a [4+3] cycloaddition of an allylium intermediate ( or ).
