26- and 27-Methyl groups of 2-substituted, 19-nor-1α,25- dihydroxylated vitamin D compounds are essential for calcium mobilization in vivo

Twelve new analogs of 19-nor-1α,25-dihydroxyvitamin D3 6-17, were prepared by a multi-step procedure from known alcohols 18 and 19. We have examined the influence of removing two methyl groups located at C-25, as well as the 25-hydroxy group, o
