    • Abstract


      Some new dimeric steroids namely cholest-5-en-3-spiro-[6'𝛼,5'-oxa]-5'$\alpha$-cholest-3'-one (2), cholest-5-en-7-spiro-[4'𝛼,5'-oxa]-5'𝛼-cholest-7'-one (4a) and 3𝛽-substitutedcholest-5-en-7-spiro-[4'𝛼,5'-oxa]-3'𝛽-substituted-5'𝛼-cholestan-7'-ones (4b, c) are synthesized starting from cholest-5-en-3-one (1), cholest-5-en-7-one (3a) and 3𝛽-substituted-cholest-5-en-7-ones (3b, c) respectively by using DMAP and xylene. All the synthesized compounds were characterized by using IR, MS and 1H, 13C NMR spectral and elemental analysis.
