Abstract
[GRAPHICS] A new, very efficient, enantioselective synthesis of the sexual attracting insect pheromone (+)-grandisol has been developed, in which the key step is the double [2 + 2] photocycloaddition of ethylene to a bis(alpha,beta-bute nolide) readily available from D-mannitol. The C-2 symmetry of the substrat e and the appropriate protection of the central diol unit are the crucial f eatures for the high diastereofacial discrimination during the cycloadditio n process.
