The preparation of museimol (a potent but toxic GABA neurotransmitter agonist), from dimethyl acetylenedicarboxylate via methyl 3-hydroxyisoxazole-5-carboxylate and the corresponding amide, has been improved and extended to a general synthesis of N-alkyl and N,N-dialkyl derivatives. The efficient route to muscimol itself [muscimol itself costs 60 -170 DM/10 mg] has enabled a study of its chemistry to be undertaken, a first result of which is its incorporation into a peptide, i.e. the preparation of N-glycylmuscimol.
Muscimol(一种强力但有毒性的GABA神经递质激动剂)的制备方法已得到改进和扩展,可以从二甲基乙炔二羧酸酯通过甲基3-羟基异恶唑-5-羧酸酯及其相应酰胺制得,并已发展为合成N-烷基和N,N-二烷基衍生物的通用方法。高效制备muscimol本身(muscimol的成本为60-170德国马克/10毫克)已使得对其化学性质的研究得以开展,首个成果是将其结合入一种肽中,即制备出N-甘氨酰muscimol。
