The title compound was divided into three retrosynthetic segments, A, B and C, by disconnecting two C-C bonds at C- and C-. Synthesis of the segment C in the optically active natural form starting from a D-glucose derivatives is described. The key features are stereochemical control which includes a methodology named heteroconjugate addition involving carbon chain extension using carbanion stabilized
