✦ Synopsis

Cycloaddition Reactions of (Z)-β-Siloxyacrylonitriles with Enones: Synthesis of 4H-Pyrans and Dihydro-2H-pyrans. -The great potential of (Z)-β-siloxyacrylonitriles as versatile synthons is proved by preparation of pyran types (III) and (V). The method is especially useful for (III) for which not many procedures are known. -(BARBERO, A.; GARCIA, C.;
