A new and efficient approach for the synthesis of oxygen and nitrogen heterocycles by organoselenium catalysis has been developed. The exo-cyclization proceeded smoothly under mild conditions with good functional group tolerance and excellent regioselectivity. Mechanistic studies revealed that 1-fluoropyridinium triflate is key for oxidative cyclization.

Compounds having antiparasitic properties are 1,2,4-trioxanes of the formula: in which:, R1 and R2 together with the adjacent carbon atom form a cycloalkyl group which may be interrupted by an oxygen atom;, R3 is a hydrogen atom or a hydroxyl gorup or eth
