Popis: | Cheleotropic extrusion of SO2 from readily prepared 3-vinyl-2,5-dihydrothiophene 1,1-dioxide 2 provides a clean and efficient route to [3]dendralene (3-methylenepenta-1,4-diene 1), the simplest member of the diene-transmissive polyenes, which contrary to previous reports is a stable, easily handled compound that shows unexpected selectivity in Diels–Alder cycloadditions, thus enhancing its utility as a tandem annelating reagent. |
