✦ Synopsis

Diosgenyl saponins were regioselectively acylated by Novozyme 435 with vinyl esters as acylating agents in THF to afford the corresponding mono-or diacyl diosgenyl saponins.

The enzymatic synthesis of 6-O-lauroylsucrose and 6-O-palmitoylsucrose was performed by transesterification of sucrose with the corresponding vinyl esters in a medium constituted by two solvents. More specifically, the acylation was carried out in 2-methyl-2-butanol (tertamyl alcohol) containing a l
