In order to elucidate the steric and plane structure of (IVα) and its isomer (IVβ) prepared by the new method of synthesis developed by the present writers, derivatives of each were prepared. For the confirmation of angular OH, dehydration and chlorination were examined and the formation of dehydrated and monochlorinated products was proved. In these reactions, a marked difference was observed in the reaction velocity between (IVα) and (IVβ) and this was assumed to be due to the difference in their steric configuration. Dehydration of (IVα) and (IVβ) afforded the same product (V) and the same monochloro compound (VI) was obtained by chlorination. It is considered that these facts offer valuable means in elucidating correlationship of the two isomers and these points will be discussed in a later report.
