G. Pohnert et al., Synthesis of volicitin: a novel three-component Wittig approach to chiral 17-hydroxylinolenic acid, CHEM COMMUN, (12), 1999, pp. 1087-1088
A short stereoselective synthesis of both enantiomers of N-(17-hydroxylinol
enoyl)-L-glutamine (volicitin) 12, an elicitor of plant volatile biosynthes
is from beet armyworm salivary secretion, is described; the protected 17-hy
droxylinolenic acid 4 moiety of volicitin 12 was prepared in a one pot bis-
Wittig reaction.
