2'- AND 3'-SUBSTITUTED SANGIVAMYCINS : CONFORMATIONAL RESTRICTION BY THE GAUCHE EFFECT

スポンサーリンク

概要

• 論文の詳細を見る

• Conformational restrictions of sangivamycin (1) could be achieved by the use of the gauche effect of the substitutents on the ribofranose moiety. The conformational deviations obtained by this method were found to nicely correlate with the inhibitory activity of PKC.
