Useful compounds in the synthesis of ciguatoxin CTX1B acids and synthetic methods of ciguatoxin CTX1B class

摘要

In total synthesis method CTX1B which was applicable in all synthesis reactions CTX1B more efficiently reactions developed in the synthesis of ciguatoxin analog such CTX3C, established, in particular, O to synthesize new compounds 3, S- acetal formation Along with the establishment reaction, until the new compound 8 from the novel compound 6, the 9-membered ring-forming reaction, total synthesis method of CTX1B including radical cyclization reaction for obtaining the compound D, and deprotection reaction for obtaining the CTX1B, and, of CTX1B are particularly useful in the synthesis, available for the synthesis of ciguatoxin analogs, novel compounds of compounds 1-8.
