Ethyl 5-methyl-3-[11-(pyridin-2-yl)-6,11-di-hydro-6,11-ep-oxy-dibenzo[b,e]oxepin-6-yl]isoxazole-4-carboxylate: a bicyclic acetal from the rearrangement of an anthracenyl isoxazole.

ABSTRACT: The title compound, C₂₆H₂₀N₂O₅, is a rearrangement product of an o-pyridinyl anthracenyl isoxazole ester. It features a bicyclic acetal structure, which has two extended almost co-planar ring systems, which subtend a fold angle of 102.17?(5)°. In the crystal, the mol-ecules are closely knitted together through C-H?N and C-H?O hydrogen bonds and form chains of alternating enanti-omers propagating along the c-axis direction.

The dihedral angle between the two benzene rings in the fused ring system is 74.66?(7)°. In the crystal, mol-ecules are linked by C-H?? inter-actions, forming a layer parallel to the ab plane. Each mol-ecule acts as a double donor as well as a double acceptor of the C-H?? inter-actions. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H?H (61.4%) and C?H/H?C (25.3%) contacts.

Bicyclic guanidine superbase carboxylate salts for cellulose dissolution.

Project description:Bicyclic guanidines are utilized in organic synthesis as base catalysts or reagents. They also offer a platform for coordination chemistry, for example in CO2 activation, and their carboxylate salts offer an efficient media for cellulose dissolution. We have studied a series of bicyclic guanidines with varying ring sizes and with varying methyl substituents with a specific aim to find hydrolytically stable acetate salts for dissolution and processing of cellulose. Different superbase synthesis pathways were tested, followed by hydrolytic stability and cellulose dissolution capacity tests. The synthesis pathways were designed to enable the scale up of the production of the superbases considering the availability of the starting molecules and the feasibility of the synthesis. As a result, we found several hydrolytically stable bicyclic guanidine structures, which can overcome many of the reoccurring problems as carboxylate salts or free bases.
