An Efficient General Method for Synthesis of Propellane and 11-Methyl-propellane

Pramod, Kakumanu,Rao, G. S. R. Subba

, p. 984 - 988 (2007/10/02)

A general method for the synthesis of propellane and 11-methyl-propellane is described.Thus the exo-alcohol (6) obtained by the addition of vinylmagnesiumbromide to the tricyclic enone (5) smoothly undergoes an Oxy-Cope rearrangement to the propellane derivative (8) which is transformed into the propellane.Similarly 11-methyl-propellane has been obtained from exo-alcohol (17).
