main active compound in liquorice root. Its aglycone, glycyrrhetinic acid, has shown several beneficial pharmacologicalactivities. This study reports the synthesis and screening of a series of glycyrrhetinic acid analogs as AChE-Is. Fourteen derivatives were prepared, of which five derivatives are recorded as new viz., 3-phenyl-carbamoyl-18β-glycyrrhetinic acid (J9), 3-acetyl-18β-glycyrrhetinic-30-anilinamide

Dehydration of methyl glycyrrhetate (VI) and β-amyrin with PCl5 and with Fuller's earth afforded ring-A contracted products in which double bond migrations may occur. HI-induced dehydration of VI afforded a conjugated enonene 18α derivative. Solvolysis of VI sulphonate esters under a variety of conditions gave a number of ring-A contracted and uncontracted products in which the new ethenoid linkage
