## Abstract A number of terminally substituted spiranes were prepared from 9โ€pentylโ€3โ€spiro[5.5]undecanone (7), which was obtained in a fiveโ€step synthesis starting from 4โ€pentylcyclohexanone (1), using an intramolecular cyclisation with 4โ€toluenesulfonylmethyl isocyanide (TosMIC) as a key step.

Synthesis and Characterization of Optically Active Spiro[4.5]decanes. -Three different dienes (I), substituted with a chiral auxiliary at the 1-position, and dienophiles (II) or (VII) undergo a Diels-Alder cycloaddition with quite good diastereofacial selectivity. The Si-exo and Re-endo diastereomer
