SYNTHESIS OF A MARINE POLYETHER TOXIN, OKADAIC ACID (3). SYNTHESIS OF SEGMENT C.

The title compound was divided into three retrosynthetic segments, A, B and C, by disconnecting two C-C bonds at C-14/15 and C-27/28.Synthesis of the segment C in the optically active natural form starting from a D-glucose derivatives is described.The key

SYNTHETIC STUDIES TOWARD MARINE TOXIC POLYETHERS (1) A STEREOCONTROLLED SYNTHESIS OF THE C-SEGMENT OF OKADAIC ACID

Okadaic acid was antithesized into three segments A, B and C, and this paper deals with the synthesis of the C-segment in the form of 24, which was prepared in 16 steps from a D-glucopyranose derivative (11) via the lactone 18.The key step is the introduc
