The crystal structure of the title compound, C(34)H(54)N(2)O(4), has been solved in order to prove the relative and absolute chirality of the newly-formed stereocentres which were established using an asymmetric Diels-Alder reaction at an earlier stage in the synthesis. This unprecedented stable dialdimine contains a 14-membered ring and was obtained as the minor diastereoisomer in the Diels-Alder reaction. The absolute stereochemistry of the stereocentres of the acetal functionality was known t ...[more]
