6-(1-Arylvinyl)-substituted 1,2,4-trioxanes undergo a highly facile fragmentation under mild basic conditions to furnish 3-aryl-l-hydroxybut-3-en-2-ones, which react very efficiently with various amines and thiols to give Michael adducts. Both the formation of the reactive 3-aryl-l-hydroxybut-3-en-2-ones and their subsequent reaction with amines and thiols can be achieved in one pot.
