Synthesis of the E Ring Segment of Ciguatoxin CTX3C via the Negishi Coupling of Cyclic Ketene Acetal Triflate
摘要:
Stereocontrolled synthesis of the E ring segment of ciguatoxin CTX3C was performed via the Negishi coupling of cyclic ketene acetal triflates. Transformation of 8-membered lactones to the corresponding ketene acetal triflates was found to be affected by the protective groups of the substrates.
