• EXTRACTIVES FROM POPULUS TREMULOÏDES HEARTWOOD: THE STRUCTURE AND SYNTHESIS OF TREMULONE
  作者：R. A. Abramovitch、R. G. Micetich

  DOI：10.1139/v62-309

  日期：1962.10.1

  Tremulone, a dienone isolated from Populus tremuloïdes heartwood, has been shown to be stigmasta-3,5-diene-7-one. This has been confirmed by a partial synthesis from β-sitosterol. The possibility that tremulone might be an artifact arising from the isolation procedure is discussed.

  Tremulone，一种从白杨木心材中分离出的二烯酮，已被证实为硬脂酸甾醇-3,5-二烯-7-酮。这已通过从β-谷甾醇的部分合成得到证实。讨论了tremulone可能是由于分离过程中产生的人为产物的可能性。
• 3β-Carboxysteranes, a novel family of fossil steroids
  作者：Fabienne Dany、Joseph Riolo、Jean-Michel Trendel、Pierre Albrecht

  DOI：10.1039/c39900001228

  日期：——

  Two 3β-carboxy-24-ethylcholestanes (24R and 24S) have been isolated as a mixture from a carbonated sediment and characterised by comparison of their mass spectrometric and 1H NMR spectroscopic data with those of synthetic standards; their origin is still unknown, since their carbon skeleton has not yet been reported in living organisms.

  从碳酸盐沉积物中分离出两种3β-羧基-24-乙基胆甾烷（24 R和24 S）的混合物，并通过将其质谱数据和1 H NMR光谱数据与合成标准品进行比较来表征。它们的起源仍是未知的，因为尚未在活生物体中报道其碳骨架。
• Convenient preparation of A-ring fused pyridines from steroidal enamides
  作者：Madan G. Barthakur、Moyurima Borthakur、Romesh C. Boruah

  DOI：10.1016/j.steroids.2008.04.016

  日期：2008.10

  A facile strategy for the preparation of A-ring fused pyridosteroids has been accomplished in high yields by the reaction of Vilsmeier reagent (chloromethyleneiminium salt) with steroidal A-ring enamides (2- and 3-ene) under thermal conditions. The structure of 6'-chloro-5 alpha-cholest [3,2-b]pyridine was determined by X-ray analysis. (c) 2008 Elsevier Inc. All rights reserved.
• Characterisation of novel 3-carboxyalkyl-steranes occurring in geological samples
  作者：Philippe Schaeffer、Fabienne Fache-Dany、Sylvie Trifilieff、Jean M. Trendel、Pierre Albrecht(rk)

  DOI：10.1016/s0040-4020(01)89396-0

  日期：1994.1

  Three novel series of 3-carboxyalkyl-steranes have been identified by synthesis in sediments from an evaporitic basin. These compounds may derive from precursor steroids bearing a polyfunctionalised side-chain at C-3, yet unknown in living organisms. Geochemical data suggest a microalgal or a bacterial origin.
