Synthesis of 24(28)-methylene-1α-hydroxyvitamin D3, a novel vitamin D3 analogue

24(28)-Methylene-1α-hydroxyvitamin D3 was synthesised in 13 steps from vitamin D2. The key step of the synthesis involved the Wittig-Horner olefination of a nor-vitamin D2 aldehyde with diethylphosphono-3-methyl-2-butanone
