|Title:||Determining ring-F configuration in spirostane-type steroidal sapogenins by 1H NMR|
|Authors:||Agrawal, Pawan K|
|IPC Code:||Int.Cl.7 C 07 J|
|Abstract:||A comparison of 1H NMR chemical shifts for 25R and 25S spirostane-type steroidal sapogenins and saponins suggest that orientation of 27-Me group has quite a different influence on chemical shifts of the methylene protons occupying -and -positions, thus providing valuable information about the establishment 25R-and 25S-stereochemistry in these compounds.|
