  Total Synthesis of 10-Norparvulenone and of O-Methylasparvenone Using a Xanthate-Mediated Free Radical Addition−Cyclization Sequence

  摘要：

  A short synthesis of (+/-)-10-norparvulenone and (+/-)-O-methylasparvenone was developed starting from commercially available m-methoxyphenol, hinging on a xanthate-mediated addition-cyclization sequence for the construction of the alpha-tetralone subunit.

• Regiospecific α-substitution of crotonic esters synthesis of naturally occurring derivatives of 6-ethyljuglone
  作者：Brigitte Caron、Paul Brassard

  日期：1991.1

  Methyl β-methoxycrotonate is alkylated regiospecifically, through the anion, in the α-position. Enolsilylation of the resulting β,γ-unsaturated ester affords the corresponding 1,1,2,3-tetrasubstituted butadiene. Cycloaddition of the latter to the appropriate halogenated benzoquinone, followed by various transformations, provides the first recorded syntheses of several natural products derived from

  β-甲氧基巴豆酸甲酯通过阴离子在α位上区域特异性地烷基化。所得β，γ-不饱和酯的烯醇化得到相应的1,1,2,3-四取代丁二烯。后者与适当的卤代苯醌进行环加成反应，然后进行各种转化，首次记录了衍生自6-乙基-7-甲氧基juglone的几种天然产物的合成。
• O-Methylasparvenone, a nitrogen-free serotonin antagonist
  作者：Michael Bös、Rolf Canesso、Noriko Inoue-Ohga、Atsuko Nakano、Yuki Takehana、Andrew J. Sleight

  O-Methylasparvenone (1) and asparvenone (2) were isolated from an Aspergillus parvulus Smith broth in a microbial screening for 5-HT2C ligands and found to be 5-HT2C antagonists. They represent the first nitrogen-free serotonin ligands. The absolute configuration of 1 was determined to be S by X-ray analysis of the corresponding Mosher-ester. A short and efficient synthesis of rac-1 was developed. This protocol was applied to the synthesis of derivatives of 1 and a structure-affinity relationship was established.
