概要
- 論文の詳細を見る
Silicagel thin-layer chromatography of several epimeric enmein derivatives, that is, compounds III-XVIII was investigated. Compounds possessing a β-OH group at C-15 were shown to be more easily adsorbed than compounds possessing a α-OH group at C-15. The unfavorable influence of C-16 β methyl group for adsorption was recognized. The most favorable effect for adsorption was provided by C-3 α equatorial OH among the compounds of group 2 in Table I (see Fig. 2).
