biochemical probes anatoxin-a and homoanatoxin have been achieved from a common intermediate using a combined two-directional synthesis-tandem reaction strategy which includes key advances in oxidative desymmetrisation, tandem Michael-intramolecular Mannich cyclisations and a new method for deprotection of N-tosyl anatoxin-a.
homoanatoxin and several analogues by a combined two-directional synthesis-tandem reaction strategy are presented. Key steps include an oxidative desymmetrisation and a tandem Michael-intramolecular Mannich cyclisation. anatoxin - homoanatoxin - two-directional - tandem - cascade - Michael - iminium - desymmetrisation
