Abstract 2-oxa ( 11 ), 2-thia ( 12 ) and 2-aza ( 19 ), 5α-cholestanes were prepared from the sulfonic esters of A-seco-2-nor-5α-cholestan-1,3-diol ( 9 and 10 ). Although cyclopentamethylenediphenylphosphonium tosylate ( 4 ) could be obtained from pentan-α,ω-ditosyloxy ( 6 ) and Ph 2 PK, attempts to prepare 3-phosphacholestane ( 16 ) in a similar ...

Hofmann degradation of 5α-cholestan-4α- and 5α-cholestan-4β-yltrimethylammonium salts
J. Chem. Soc. B, 1970Alkaline degradation of 5α-cholestan-4α-yltrimethylammonium iodide gives mainly 5α-cholestan-4α-yldimethyl-amine with a little cholest-3-ene, while the 4β-isomer gives cholest-4-ene. The unstable 4β-iodide also readily yields cholest-4-ene in boiling neutral alcohol.
