## Abstract The isomerization reaction of cholest‐5‐en‐3‐one has been studied in a solution of cyclohexane using trichloroacetic acid as catalyst. At the same time a general reaction scheme is proposed to be valid for all the cases assayed in which the monomer form of the acid is considered as the
The 13C N M R spectra of nineteen bromo derivatives of 5ru-cholestan-3-one, cholest4-en-3-one and cholest-5-en-3one have been recorded. The substituent effects are analysed and examined with respect to additivity. The more interesting ys,,, and ylmti effects are considered in detail. KEY WORDS 13C
## The stereochemical course of the epoxide-induced oxidative rearrangement of ribonucleoside cyclic 3',5'phosphorothioates into the corresponding 2',3'-phosphates has been determined using styrene ['80] oxide and (Sp)-uridine cyclic 3',5'-phosphorothioate. The evidence of full stereoselectivity of
During the attempted preparation of the p-toluenesulphonylhydrazone of enone 2 it has been established that a reductive side reaction occurs -probably brought about by di-imide, arising from the thermal decomposition of p-toluenesulphonylhydrazine. In connection with our studies 1 directed towards t
