ChemInform Abstract: Studies on the Carbon Zip Reaction of 2‐Oxocycloalkane‐1‐carbonitriles.

Abstract

The formation of ring‐enlarged products (II) from the title compounds (I) is influenced both by the lengthof the side chain and by the size of the ring system [8‐ and 12‐membered Substrates; the CN group acts as a charge stabilizer in the course of the ring opening step of the alkoxide intermediate analogous to (VI)].
