An asymmetric total synthesis of [13C4]-anatoxin-a ([13C4]-1) has been developed from commercially available ethyl [13C4]-acetoacetate ([13C4]-15). The unique requirements associated with isotope incorporation inspired a new, robust, and highly scalable route, providing access to 0.110 g of this internal standard for use in the detection and precise quantification of anatoxin-a in freshwater. A highlight of the synthesis is a method that leverages a cyclic iminium ion racemization to achieve dynamic kinetic resolution in an enantioselective Morita–Baylis–Hillman (MBH) cyclization.
Investigation of a unified strategy for the synthesis of anatoxin analogues: Scope and limitations
Roe, Stephen J.,Hughes, David L.,Aggarwal, Pooja,Stockman, Robert A.
experimental part, p. 3775 - 3784 (2010/03/30)
Syntheses of the potent neurotoxins and biochemical probes anatoxin-a and homoanatoxin and several analogues by a combined two-directional synthesis-tandem reaction strategy are presented. Key steps include an oxidative desymmetrisation and a tandem Micha

The synthesis and stereocontrolled Ag1-catalysed cyclisation of a series of allenic amino esters 8a-e is described.For compounds 8a-d the cis-2,5-disubstituted pyrrolidine 9 is formed exclusively but the primary amine 8e undergoes cyclisation n
