Abstract
A compound of the formula (I): and a compound of the formula (V): as well as a compound of the formula (X): which are each a novel siastatin B derivative having a potent inhibitory activity against a glycosidase, are now synthesized by new processes.The compound of the formula (I), the compound of the formula (V) and the compound of the formula (X) have a potent enzyme-inhibitory activity to a glycosidase, which is particularly N-acetyl-galactosaminidase, galactosidase, glucosidase and mannosidase.
