Total synthesis of 25-hydroxy-16,23E-diene vitamin D3 and 1α,25-dihydroxy-16,23E-diene vitamin D3: Separation of genomic and nongenomic vitamin D activities

Separation of genomic and nongenomic vitamin D activities was achieved by structural modification of 1,25-dihydroxy vitamin D3 by introduction of 16 and 23E double bonds. The modified compound 3, lacking a 1α-hydroxy group, exhibits only nongen
