• Synthesis of the C1-C13 Fragment of Kendomycin: Atropisomerism around a C−Aryl Glycosidic Bond
  作者：Harry J. Martin、Martina Drescher、Hanspeter Kählig、Sabine Schneider、Johann Mulzer

  DOI：10.1002/1521-3773(20010903)40:17<3186::aid-anie3186>3.0.co;2-w

  日期：2001.9.3

  The left-hand fragment 2 of the novel antibiotic kendomycin (1) has been synthesized by an aldol addition and a Michael-type 1,4-addition of a C5 alcohol with a C9-C11 enone. Compound 2 shows an interesting atropisomerism around the C4a-C5-sp2 -sp3 bond. The atropisomers can be separated in pure forms by low-temperature high-pressure liquid chromatography.

  作者：Rachel H. Carter、Mary J. Garson、Robert A. Hill、James Staunton、David C. Sunter

  DOI：10.1039/p19810000471

  日期：——

  A flexible synthetic route leading via indan-1-ones to variously methylated and oxygenated isocoumarins is described. The indanones are prepared by alternative routes involving intramolecular Friedel–Crafts cyclisation of aryl-propionic acids or pericyclic ring closure of acrylophenones. The influence of substitution on the rate of the pericyclic reaction is assessed.
