  Synthesis of Conjugated γ- and δ-Lactones from Aldehydes and Ketones via a Vinylation/Allylation-Ring Closing Metathesis-Oxidation Sequence

  摘要：

  通过对醛和酮进行亲核碳乙烯基化或碳烯丙基化反应，随后对所得卡宾醇进行氧烯丙基化，得到了相应的烯丙醚。后者经过环闭合易位反应，分别得到环醚（二氢呋喃和二氢吡喃），再经过烯丙位的氧化反应，分别生成共轭的γ-和δ-内酯。

  aldehydes and ketones followed by O-allylation of the obtained carbinols gave the corresponding allyl or homoallyl ethers, respectively. Ring-closing metathesis of these compounds afforded in many cases cyclic ethers (dihydrofurans and dihydropyrans, respectively) bearing disubstituted and trisubstituted CC bonds. These were then subjected to allylic oxidation to yield conjugated γ- and δ-lactones. Reasons

  醛和酮的亲核C-乙烯基化和C-烯丙基化，然后将得到的甲醇进行O-烯丙基化，分别得到相应的烯丙基或高烯丙基醚。这些化合物的闭环易位在许多情况下提供带有二取代和三取代的CC键的环状醚（分别为二氢呋喃和二氢吡喃）。然后将它们进行烯丙基氧化以产生共轭的γ-和δ-内酯。介绍并讨论了观察到的故障的原因。

  Retinoids that activate the nuclear retinoid X receptors (RXRs) display potential for chemo-prevention of breast cancer. We previously reported that 9cUAB30 (1) is an RXR-selective retinoid. To explore its in vivo chemopreventive activity, multigram quantities of 1 were needed. Here, we describe a modified synthesis that yields up to 100 g of 1. We further demonstrate that 1 is very effective in the prevention of N-methyl-N-nitrosourea induced mammary cancers in rats without signs of toxicity.
