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
