  Novel iodine catalyzed diastereoselective synthesis of trans-2,6-disubstituted tetrahydro-2H-pyrans: synthesis of C1–C13 fragment of bistramide-A

  摘要：

  A new method for the stereoselective synthesis of trans 2.6-disubstituted tetrahydro-2H-pyrans has been developed involving iodine catalyzed allylation of tetrahydro-2H-pyranol with excellent trans selectivity. The method was also applied toward the construction of C1-C13 fragment of bistramide-A in 11 steps with 21.4% overall yield. (C) 2013 Elsevier Ltd. All rights reserved.

  An improved synthesis of (−)-brevisamide a marine cyclic ether isolated from the red-tide dinoflagellate Karenia brevis was achieved. The ether ring portion was constructed from an unsaturated lactone, which was prepared enantioselectively via an Evans aldol reaction and one-pot lactonization in the presence of excessive base after an Ando reaction. The ether ring and a dienol side chain fragment were
