  Total Synthesis of Trilobin

  摘要：

  The first total synthesis of(+)-trilobin (la) was achieved in 22 steps and 2.74% yield by means of the "naked" carbon skeleton strategy, with all of the asymmetric centers in the bis-THF fragment of the molecules being produced by the Sharpless asymmetric dihydroxylation and the asymmetric epoxidation reactions. The synthetic scheme represents a general methodology for the preparation of trans,cis-bis-THF ring systems.
