9,10‐Secocholesta‐(5 Z )‐5,8(14),10(19)‐triene‐3β‐ol and 18‐Nor‐14β‐methyl‐9,10‐secocholesta‐(5 E )‐5,10(19), 13(17)‐trien‐3β‐ol, two new double bond isomers of vitamin D 3 . Structural modifications of vitamin D 3 : 5. Communication [1] The present paper reports the synthesis and structure elucidation of the two title compounds. Treatment of the 4‐phenyl‐1,2,4‐triazolin‐3,5‐dione adducts of vitamin D 3 with BF 3 O (C 2 H 5 ) 2 and KOH/butanol yields these two new vitamin D 3 double bond isomers.
