Diels-Alder Reactions of [1]Benzothieno[3,furan. -The Diels-Alder reaction of benzothienofurans (I) with substituted dienes leads to tetrahydrobenzothienobenzofuran derivatives (III) with excellent endo-stereoselectivity. Aromatization of the products yields newly fused benzothieno[3,2-b]benzofuran
## Abstract The kinetics of the reactions of 1,2‐diaza‐1,3‐dienes **1** with acceptor‐substituted carbanions **2** have been studied at 20 °C. The reactions follow a second‐order rate law, and can be described by the linear free energy relationship log __k__(20 °C)=__s__(__N__+__E__) [Eq. (1)]. Wit
