✦ Synopsis
In our recent paper 2 it was reported that the photoinduced hypoiodite reaction of cholesterol (1) or epicholesterol (2) with HgO and I2 in benzene under an argon atmosphere afforded two iodine-containing products ( 3) and ( 4)
and 4-iodo-3,4-seco-cholest-5-en-3 al (5). Oxidomethylene-3a,5a-A-norcholestane structures (A) and (B) were proposed for these iodine-containing products on the basis of the 1 H n.m.r. and the spin-decoupling experiments of these compounds and the D-incorporated compounds as well as consideration of probable mechanistic pathways of their formation.
In this paper we wish to report that the proposed structures for these two compounds are not correct and

We have discovered that chlorine in 3~-acetoxy-17-chloro-16-formylandrosta-5,16-diene (1) can be smoothly displaced by nitrogen heterocyclic nucleophiles (her) to give heretofore unknown 17-substituted-A t6 steroids in high yields (73-92%). This enabled us to synthesize novel 3~-hydroxy-17-(1H-1,2,4
