PHOTOLABILE PRO-FRAGRANCES

Many fragrances that provide a scent of freshness tend to be highly volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used efficiently.

Synthesis and reactivity of methyl 3-acyl-6-amino-4-aryl-5-cyano-4h-pyran- 2-carboxylates

By treating arylidenemalononitriles with methyl 2,4-dioxobutanoates, derivatives of 4H-pyrans - methyl 3-acyl-6-amino-4-aryl-5-cyano-4H-pyran-2- carboxylates - are obtained, which are novel, promising structural components for the synthesis of carbo- and
