2,6-exo-8,12-exo-10-Butyl-13-oxa-3,5-dithia-10-azatetracyclo[5.5.1.02,6.08,12]tridecane-9,11-dione

Abstract

The title compound was obtained in low yield and spectroscopically characterised. Its X-ray structure was compared with the X-ray structures of other crystallographically-characterised 2-unsubstituted 1,3-dithiolanes.

“…The re ing molecular structure (Figure 2) confirms the exo, exo-configuration and has the epo and imide rings at angles of 69.4° and 61.5° to the norbornane core, respectively. A selection of similar norbornane compounds with fused 3-and 5-membered r that have been crystallographically characterised is shown in Figure 3 with CCDC r ence codes, literature references, and angles [18][19][20]. Several features of this are of interest, including the dramatic shielding of the carbon bridge and only one of its protons on moving from alkenes 1 and 2 to epoxides 4 and 3, significant deshielding of the bridgehead (1/7) carbons but not protons in moving from alkenes to epoxides, and the cross-over in order between H and C signals for 1/7, 2/6, and epoxide positions in all four compounds.…”
