26-Desmethyl-2-methylene-22-ene-19-nor-1α,25-dihydroxyvitamin D 3 compounds selectively active on intestine

Six new analogs of 2-methylene-19-nor-1α,25-dihydroxyvitamin D 3, 6-7 and 8a,b-9a,b, have been synthesized. All compounds are characterized by a trans double bond located in the side chain between C-22 and C-23. While compounds 6 and 7 possess
