✦ Synopsis

Ozonolyses of 4,4-Dimethyl-2-cyclohexen-1-yl Acetate and 4,4-Dimethyl-2-cyclopenten-1-yl Acetate. Competition Between the Steric Effects of the Allylic Methyl Groups and the Electronic Effects of the Acetoxy Group on the Direction of Cleavage of the Primary Ozonides.

-The title effects are investigated in the ozonolysis of compounds such as (I)-(III) in methanol or in ether in the presence of trifluoroacetophenone. The results are discussed in detail. -(KAWAMURA,
