Synthesis of 2-methyl and ethyl-substituted 19-nor-1α,25- dihydroxyvitamin D3 analogues via the cyclovitamin strategy

The synthesis of several 19-nor-2-alkyl-1α,25-dihydroxyvitamin D 3 analogues (5-14) is described following the cyclovitamin strategy. Starting from all-cis methyl 3,5-dihydroxy-4-alkyl-1-cyclohexanecarboxylate (29), the eight stereoisomeric A-r
