Synthetic approaches to the southern part of cyclotheonamide C
摘要:
A synthetic equivalent of the Southern segment of cyclotheonamide C, a cyclopentapeptide isolated from the sponge Theonella, has been synthesized via complementary Wadsworth-Emmons or palladium-catalysed methodologies followed by tandem oxidation/vinylogation in 41% overall yield (five steps) front readily available starting materials.
