2,4-Diazabicyclononane Skeletons from cis-Benzene Trioxide

By treating cis-benzene trioxide (1) with guanidine in buffered tert-butyl alcohol solution the 1:1-adducts DL-(1α,2β,4β,5α,6α,10α)-8-imino-3-oxa-7,9-diazatricyclo2,4>decane-5,10-diol (13a) and DL-(1α,2α,3β,5β,6α,7α)-9-imino-4-oxa-8,10-diazatricyclo3,5>decane-2,6-diol (12a) resulting from 1,3(1,2)-bridging in 1 are obtained in 88-91percent (9-12percent) yields.Trifluoroacetamidine (acetamidine) is also selectively 1,3-added to 1.From 13a via generally regiospecific hydrolysis (26a), thiolysis (30a, d), ammonolysis (34a), hydrazinolysis (34d), and HCl-/HBr-addition (39a, c) access to highly functionalised 2,4-diazabicyclononane derivatives is opened.During the "ring-chain tautomerism" observed for 26a and 34d (28a, 36d) the adamantoid orthocarbonic acid intermediates (27a, 35d) cannot be identified directly.The spectroscopic structure elucidations (not always unequivocal because i.a. of conformational flexibility of the skeletons) are confirmed by X-ray structural analysis for 29f, 36e, 38, and 43.
