Photochemical synthesis of C/D-ring synthons of vitamin D

Beginning with a steroid-5-ene, C/D-ring synthons of vitamin D are readily prepared via ozonization followed by a Norrish II photoelimination reaction.

SYNTHESIS AND PHOTOCHEMISTRY OF 5-HYDROXY-5β-CHOLEST-3-EN-6-ONE

Reaction of 3β-benzyloxy-5-hydroxy-5α-cholestan-6-one (1) with potassium t-butoxide in t-butyl alcohol gives 5-hydroxy-5β-cholest-3-en-6-one (2), which on direct irradiation (300 nm) in hexanes gives the B-seco steroid 9 and the indenacetaldehyde derivative 10.
