Y. Ye et al., BIOSYNTHESIS OF THE AZOXYCARBOXAMIDE LYOPHYLLIN AND FORMATION OF SOMEOF ITS UNNATURAL ANALOGS IN FRUIT-BODIES OF LYOPHYLLUM-CONNATUM, Tetrahedron letters, 38(46), 1997, pp. 8013-8016
The azoxy compound lyophyllin (3) is formed in fruit-bodies of the toa
dstool Lyophyllum connatum by oxidative condensation of N-hydroxy-N'N'
-dimethyiurea (2) with N-methylhydroxylamine (4). The condensing enzym
e is remarkably unspecific and transforms a variety of hydroxyureas an
d N-alkyl-hydroxylamines into the corresponding lyophyllin analogues 5
