Detailed herein is the tethered Biginelli condensation between irninium ion 201 and beta keto ester 206 leading to a model tricyclic ring system representative of the guanidinium core of cylindrospennopsin alkaloids. This was achieved in a biosynthetically-inspired manner in 12 steps and 8.3% overall yield from simple, commercially available 1,5-pentanediol 172. Also discussed is the adaption of this methodology to allow for the highly efficient stereoselective synthesis of all 3 of the cylindrospermopsin alkaloids and the preparation of the advanced synthetic intermediate nitro-alcohol 223.
