Synthesis of the protected tetrasaccharide II is reported as the key intermediate of tetrasaccharide from laminin that is an important glycoprotein on the basement membrane.
Cimicifugamide, a new natural compound isolated from the roots of Cimicifuga dahurica, was totally synthesized by a reaction sequence of seven steps in an overall yield of 31 %.
