  Total synthesis of AAL-toxin TA1

  摘要：

  Two alternative synthetic routes of the left-half segment 5 have been developed. Efficient condensation between the left and right segments followed by Pd-catalyzed deoxygenation and further elaboration achieved the first total synthesis of AAL-toxin TA(1). This allowed us to synthesize various AAL-toxin analogs which would be useful for investigating SAR studies of AAL-toxins. (C) 1999 Elsevier Science Ltd. All rights reserved.

• Studies on a Urea-Directed Stork−Crabtree Hydrogenation. Synthesis of the C1−C9 Subunit of (+)-Zincophorin
  作者：Zhenlei Song、Richard P. Hsung、Ting Lu、Andrew G. Lohse

  DOI：10.1021/jo7017922

  日期：2007.12.1

  [GRAPHICS]A detailed account on the stereoselective synthesis of the C1-C9 subunit of (+)-zincophorin is described here. This approach features the first application of a stereoselective inverse electron demand hetero-[4 + 2] cycloaddition of chiral allenamides in natural product synthesis. The C1-C9 subunit matches Cossy's intermediate, thereby constituting a formal total synthesis. In addition, details of an unusual urea-directed Stork-Crabtree hydrogenation observed during these efforts are also disclosed here.

  DOI：10.1021/ol070791a

  日期：2007.5.1

  A formal total synthesis of (+)-zincophorin via interception of Miyashita's advanced intermediates is described here. This effort features the first synthetic application of an inverse demand hetero [4 + 2] cycloaddition of a chiral allenamide, and the observation of an unusual urea directed Stork-Crabtree hydrogenation.
