Synthesis and complete 1H, 13C and 15N NMR assignment of substituted isoxazolo[3,4-d]pyridazin-7(6H)-ones.
The synthesis and complete assignment of all hydrogen, carbon and nitrogen NMR signals of several new isoxazolo[3,4-d]pyridazin-7(6H)-ones is reported. The spectroscopic characterization is extended to previously described analogues.
