Design and synthesis of isoxazole containing bioisosteres of epibatidine as potent nicotinic acetylcholine receptor agonists

An efficient synthesis of isoxazole containing isosteres of epibatidine is described. The synthesis proceeded from N-tert-butoxycarbonyl (Boc)-exo-2-(methoxycarbonyl)-7-azabicyclo[2.2.1]heptane (9). Compound 9 was reacted with the dilithium salt of an appropriately substituted oxime in tetrahydrofuran (THF), Cyclodehydration of the resultant beta-keto oxime and deprotection of the N-Boc group in 5 N aqueous HCl afforded the isoxazole containing isosteres of epibatidine (6-8), The binding affinities of these compounds were determined at the nicotinic acetylcholine receptor for the displacement of [H-3]cytisine. The unsubstituted isoxazole containing isostere (6) showed the lower binding potency compared to the 3′-methylisoxazole isostere (7), Substitution with a phenyl group at the 3′-position of the isoxazole significantly reduced the binding potency. The in vivo toxicological studies of these analogs were also performed, The LD50 of the analogs ranged in the order: Me>H>Ph.

A series of cycloadducts via 1,3-dipolar cycloaddition reactions of generated nitrile oxides with N-(4-chloro-2-fluorophenyl)maleimides were described. The reaction of N-(4-chloro-2-fluorophenyl)maleimides with nitrile oxides gave 3,5-diaryl-3a,6a-dihydropyrrolo[3,4-d]isoxazole-4,6-diones through syn-addition pattern. The title compounds were characterized by (HNMR)-H-1, IR, MS, and elemental analysis or HRMS. The single crystal structure of 6i was determined by X-ray diffraction. The herbicidal activities of the title compounds were evaluated. Some of them exhibited certain herbicidal activities against barnyardgrass and rape.

Isoxazole mediated synthesis of 4-(1H)pyridones: improved preparation of antimalarial candidate GSK932121

A new synthesis of the antimalarial clinical candidate GSK932121 is described. This approach has two key reactions, the selective acylation of an unprotected 3-hydroxymethyl-5-methyl isoxazole and the reductive N-O bond cleavage of the previously functionalized isoxazole derivative, to give the 4-(1H)pyridone ring present in the final structure. The complete synthesis consists of 5 steps (versus 10 steps in previously published reports) and has enabled the preparation of the material in kilogram scale to support clinical studies.
