Steroid halogen-containing

Fig. 2 Regression equations should only be carried out on sets of sufficiently similar compounds otherwise the occurrence of outliers is highly likely. Here shown for the corticosteroid-binding globulin (CBG) activity of steroids. Experimental data were taken from ref 10. Left The depicted substance is the only halogen-containing molecule in this set. Right Removing this outlier from the data set yields a more consistent picture showing improved statistical quantities.

Sulfated derivatives are ubiquitous in the ophim-oids, and indude hydrocarbons, carotenoids, sterols, polyhy-droxysterols and steroidal glycosides. No nitrogen- or halogen-containing secondary metabobtes seem to have been isolated. 

Molecular structure and thermochemistry are interrelated here for species chosen from contributions to the earlier Volume 3 of this book series. Discussion includes halogenated species gaseous nonmetal dioxides X-Y bond-containing species (X,Y = C, N, O) small carbon molecules arenols and substituted arenes steroids aromatic carbocycles difluoramines and nitro compounds selenium- and tellurium-nitrogen compounds. 

The cholest-6-en-la,3P-diol (106) obtained in Mazxjr s liquid ammonia reduction of la,2a-epoxycholesta-4,6-dien-3-one has been brominated to give the corresponding 6,7-dibromide which was dehydro-halogenated in hexamethylphosphoramide containing triethyl methyl ammonium dimethylphosphate to give a mixture (1.3 1) of the 5,7-and 4,6-diene compounds (57). As mentioned above treatment of steroidal...
