摘要:Short syntheses of 24-thia-5 alpha,20 xi-cholestan-3 beta-ol, 24-methyl-24-aza-5 alpha,20 xi-cholestan-3 beta-ol, and 24-nor-5 alpha,20 xi-cholan-3 beta-ol from 3 beta-hydroxy-5 alpha-pregnan-20-one are described. The products and synthetic intermediates have been fully characterized by the results of proton NMR, infrared, and high and low resolution mass spectral studies.
