Total Synthesis of (‐)‐Strychnine.
ChemInform, 2004Total synthesis of (-)-strychnine is described. Notable features of our synthesis include (1) palladium-catalyzed coupling of the indole and vinyl epoxide moieties, (2) synthesis of the nine-membered cyclic amine derivative from the diol precursor in a one-pot procedure, and (3) transannular cyclization of the nine-membered cyclic amine.

The diazotisation of 6,7-dimethoxy- and 7-ethoxy-6-methoxy-1-(2-amino-4,5-methylenedioxybenzyl)-1,2,3,4-tetrahydro-2-methylisoquinoline (XII) and (XV), followed by thermal decomposition, gave amurine (Ib), as a result of which Dopke's structure for the alkaloid was proved to be correct.

Total Synthesis of (−)-Agelastatin A
Organic Letters, 2008A new route to (-)-agelastatin A is reported. The requisite nitrogen functionalities of the agelastatin core have been installed by intramolecular aziridination of an azidoformate and subsequent regioselective azidation, leading to net trans-diamination of the double bond. The present synthesis also demonstrates two new protocols for the preparation of
