A simple one-pot synthesis of spiranones from cycloketones and dienes promoted by an ammonium salt generated in situ from diamine and alkoxymethyl chloride through a tandem alpha-methylenation/Diels-Alderreaction is described.
The synthesis and the antimalarial activity of a new kind of polycyclic 1,2,4-trioxanes are reported. The alkylation of the heme model MnIITPP by the biologically active (IC 50 = 320 nmol L-1) hemiperketal 2 is presented.
