Reference Reading
1. Studies directed toward the synthesis of terreulactone A: rapid construction of the A, B, C rings
Haibo Liu, Dionicio R Siegel, Samuel J Danishefsky Org Lett. 2006 Feb 2;8(3):423-5. doi: 10.1021/ol052618p.
[structure: see text]. An efficient, rapid synthesis of the A, B, C rings of terreulactone A is described. Key steps in the synthesis include a diastereoselective benzylic acid rearrangement to create the desired quaternary center at C2 and a mild bromolactonization to assemble the lactonic ring A.
2. Bioactive α-pyrone meroterpenoids from mangrove endophytic fungus Penicillium sp
Bo Ding, Zhiyuan Wang, Xishan Huang, Yayue Liu, Wenrui Chen, Zhigang She Nat Prod Res. 2016 Dec;30(24):2805-2812. doi: 10.1080/14786419.2016.1164702. Epub 2016 Apr 11.
Five α-pyrone meroterpenoids, including one new 3-epiarigsugacin E (1) and four known compounds, arisugacin D (2), arisugacin B (3), territrem C (4) and terreulactone C (5) were obtained from the marine fungus Penicillium sp. SK5GW1L. Their structures were identified by MS and NMR experiments, and the absolute configuration of compound 1 was further confirmed by low temperature (150 K) single crystal X-ray diffraction with Cu Kα radiation. Compounds 3, 4 and 5 showed strong inhibitory activities against acetylcholinesterase (AchE) with IC50 values of 3.03, 0.23 and 0.028 μM, respectively.
