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

VITAMIN D ANALOGUES AND THEIR THERAPEUTIC USES

The present invention relates to analogues of vitamin D namely 14-epi-2-alkyl-19-nor vitamin D derivatives. Also a general method for the synthesis and the biological activities are described. The general formula is: (I) where R (alpha or beta oriented) r

A convenient, large scale synthesis of trans-(+)-sobrerol

A convenient and highly efficient synthesis of optically pure trans(+)-sobrerol (1), starting from methyl 3,5-dihydroxy-4-methyl benzoate 2 in 8 steps with overall yield 26%, is reported. The key intermediate 4 is prepared in remarkably high yield by selectively esterification of 3 using lipase as catalyst. A critical step to stereoselectively inverse the configuration of 7 is realized under Mistunobu conditions.
