of related sulfoxides. In all cases lactam formation by attack of HN3 on the carbonyl group of the keto sulfoxide appears to predominate, with no evidence for sulfoximine formation. The question of aryl vs. alkyl migration, as in other systems, is dependent on the degree of substitution of the alkyl group. When the Schmidt reaction was carried out upon thiochromone 1,1-dioxide two products, the lactam
