  Synthesis and Biological Activity of Kalkitoxin and its Analogues

  摘要：

  Total syntheses of kalkitoxin, isolated from the Caribbean Lyngbya majuscula, and its analogues, 3-epi-, 7-epi-, 8-epi-, 10-epi-, 10-nor-, and 16-nor-kalldtcocin, were achieved via oxazolidinone-based diastereoselective 1,4-addition reaction of a methyl group and efficient T1C14-mediated thiazoline ring formation as the key steps. The biological activities of synthetic kalkitoxin and its analogues were evaluated with brine shrimp.
