Abstract

I. THE SYNTHESIS OF 2-ALK Y L-4-HYDROXY- 1 -CYCLOPENTANONES AND DERIVATIVES ... The metal-ammonia reduction of 2-alkyl-4-hydroxy-3-methoxy-2-cyclo- pentene-1-ones, (111) gives 2-alkyl-4-hydroxy-1-cyclopentanones (IV) and 4-alkyl-l,3-cyclopentanediols (V). The former products can easily be dehydrated to 5-alkyl-2-cyclopenten- 1-ones (VI). ... In a previous communication (''1 the metal-ammonia reduction of methyl enol ethers of 3-alkyl- 1,2, ...
