Copper-mediated alkylation of vitamin D C-ring. Synthesis of C11-functionalized 1α,25-dihydroxyvitamin D3
摘要:
This work describes our studies on the functionalization at C11 of CD-ring fragments of vitamin D-3 using organocopper reagents. As an application, an efficient, convergent synthesis of 11 alpha-[3,3-(dimethoxy)propyl] calcitriol analogue 2, which may be useful for the construction of affinity columns for the purification of 1 alpha,25-(OH)(2)-vitamin D-3 receptors, is described.
