Is. Blagbrough et al., ACYLATION OF LYCOCTONINE - SEMISYNTHESIS OF INULINE, DELSEMINE ANALOGS AND METHYLLYCACONITINE, Tetrahedron letters, 35(46), 1994, pp. 8705-8708
Lycoctonine has been acylated to afford sequentially inuline, delsemin
e analogues and methyllycaconitine using isatoic anhydride followed by
S-(-)-methylsuccinic anhydride. This protocol is a rapid, facile meth
od for the regiospecific introduction of the anthranilate ester moiety
found in potent nicotinic acetylcholine receptor antagonists.
