  Camphor-derived amber/woody odorants: 1,7,7-trimethyl-2′-iso-propylspiro[bicyclo[2.2.1]heptane-2,4′-(1,3-dioxanes)]

  摘要：

  Six stereoisomers of a new camphor-derived 1,7,7-trimethyl-2'-iso-propylspiro[bicyclo[2.2.1]heptane-2,4'-(1,3-dioxane)] odorant were prepared. Their design with the help of an amber olfactophore model and structure-odour relationship are reported. The (IR,2S,4R,2'S) isomer has by far the strongest and the most characteristic amber-like odour. (C) 2001 Elsevier Science Ltd. All rights reserved.

• Synthesis of new optically active 1,3-diols with camphor and fenchone skeleton

  日期：1994.10

  The new optically active 1,3-diols 5–8 with (1R)-(+)-camphor and (1R)-(−)-fenchone skeleton were synthesized in high yields from the homoallylic alcohols 1–4 using a very effective ozonolysis followed by reduction. The absolute configuration of (1R, 2S, 12R)-6a was determined by a single crystal X-ray study.

• Preparation of Chiral Hydroxy Carbonyl Compounds and Diols by Ozonolysis of Olefinic Isoborneol and Fenchol Derivatives: Characterization of Stable Ozonides by1H-,13C-, and17O-NMR and Electrospray Ionization Mass Spectrometry

  The allylic and homoallylic alcohols 1-8, prepared from (+)-camphor and (-)-fenchone, were ozonized in Et2O at -78 and treated with Et3N or LiAlH4 to give the chiral hydroxy carbonyl compounds 9-16 and the diols 17-24, respectively (Scheme I). In the case of the diols 19 and WI the formation of new chiral centers proceeded with high diastereoselectivity. These diols were prepared highly diastereoselectively also by LiAlH4 reduction of the hydroxy carbonyl compounds 11 and 16a, respectively (Scheme 2). The absolute configuration of the new chiral centers in 19 and 24 was determined by X-ray and NMR methods. The ozonization of compounds 2, 3, 7, and 8 provided the relatively stable hydroxy-substituted 1,2,4-trioxolane derivatives (ozonides) 37-40 (Scheme 5) which were characterized by H-1- and C-13-NMR spectra. ESI-MS, and natural-abundance O-17-NMR spectra.
