  An efficient synthesis of 2-cyclopentenones from γ-ketoaldehyde acetals using lithium trimethylsilyldiazomethane. Its application to the synthesis of trichodenone C

  摘要：

  The reaction of gamma-ketoaldehyde acetals with lithium trimethylsilyldiazomethane afforded 2-cyclopentenones via the 1,5-C-H insertion of alkylidene carbene in high to moderate yields. Using this method, the synthesis of trichodenone C was achieved. (C) 2000 Elsevier Science Ltd. All rights reserved.

• Bioinspired Total Synthesis and Stereochemical Revision of the Fungal Metabolite Pestalospirane B
  作者：Sandhya Badrinarayanan、Christopher J. Squire、Jonathan Sperry、Margaret A. Brimble

  DOI：10.1021/acs.orglett.7b01371

  日期：2017.7.7

  The total synthesis of both enantiomers of pestalospirane B, 2, has been achieved using a bioinspired tandem dimerization–spiroketalization reaction. Electronic circular dichroism (ECD) and X-ray analysis were used to revise the absolute stereochemistry of the natural product pestalospirane B from 3S, 3′S, 12R, 12′R to its enantiomer 3R, 3′R, 12S, 12′S.

  使用生物启发的串联二聚化-螺缩酮化反应已实现了香豆螺烷B，2的两个对映异构体的总合成。电子圆二色性（ECD）和X射线分析被用来从3修改天然产物pestalospirane B的绝对立体化学小号，3'小号，12 - [R，12' - [R到其对映体3 - [R，3' - [R，12小号，12 'S。
• Syntheses of (−)-Tatarinoid A, (±)-Tatarinoid B, and (−)-Tatarinoid C
  作者：Yuriy Slutskyy、William T. Jewell、Claudia G. Lucero

  DOI：10.1016/j.tetlet.2012.10.104

  日期：2013.1

  The syntheses of (-)-Tatarinoid A, (+/-)-Tatarinoid B, and (-)-Tatarinoid C in one to three steps are described herein. (-)-Tatarinoid A and (-)-Tatarinoid C are both constructed in three steps from 1-bromo-2,4,5-trimethoxybenzene in overall yields of 63% and 74%, respectively. The addition of (1-methoxyethyl)triphenylphosphonium ylide to 2,4,5-trimethoxybenzaldehyde provides (+/-)-Tatarinoid B in one step in 97% yield. Published by Elsevier Ltd.

  The title acid, a component of microsclerodermins of marine sponge origin having five consecutive stereogenic centers, was efficiently synthesized as its protected form 1 from the alcohol 5 utilizing the stereoselective addition of anisole to the acetylenic triple bond and the anti-aldol reaction as key steps.
