Versatile synthesis and biological evaluation of 1,3-diamino-substituted 1α,25-dihydroxyvitamin D3 analogues

A concise route to 1α,3β-diamino-25-hydroxy-3-deoxyvitamin D3 (5) and 1β,3α-diamino-25-hydroxy-3-deoxyvitamin D 3 (6) has been developed starting from (R)- or (S)-carvone for the construction of the modified A-ring fragments. The con
