  • Enantioselective construction of alicyclic bicyclo[3.1.0]hexane framework by double stereodifferentiation and its application for the synthesis of both enantiomers of vitamin D3 CD ring synthons
    作者:Mingqi He、Shinji Tanimori、Susumu Ohira、Mitsuru Nakayama
    DOI:10.1016/s0040-4020(97)00869-7
    日期:1997.9
    reaction was catalyzed by a chiral bis-oxazoline copper (l) complex 17. The absolute stereochemistry of each generated diastereomer (10f and 11f) was elucidated. Both enantiomers of the vitamin D3 CD ring synthons ((−)-21 and (+)-22) were synthesized from (−)-12 and (+)-13, respectively.
    在具有(R)-泛内酯作为手性助剂的手性不饱和α-重氮-β-酮酸酯9f的分子内环丙烷化中观察到良好的非对映选择性(85:15)。该反应由手性双-恶唑啉铜(l)配合物17催化。阐明了每种生成的非对映异构体(10f和11f)的绝对立体化学。维生素D 3 CD环合成子的两种对映体((-)- 21和(+)- 22)分别由(-)- 12和(+)- 13合成。
  • A Concise Synthesis of <i>ent</i>-Cholesterol
    作者:Jitendra D. Belani、Scott D. Rychnovsky
    DOI:10.1021/jo702694g
    日期:2008.4.1
    ent-Cholesterol was synthesized in 16 steps,from commercially available (S)-citronellol. The overall yield for the synthesis was 2.0%. This route is amenable to gram-scale preparation of ent-cholesterol. Isotopic incorporation near the end of the synthesis was achieved using labeled methyl iodide. This synthesis is the most practical to date and will make ent-cholesterol more readily available to use as a probe of the function and metabolism of cholesterol.
  • Synthesis of a Vitamin D<sub>3</sub> Hydrindan Ring−Side-Chain Building Block, Involving Tandem Conjugate Addition and Alkylation Reactions
    作者:Paweł Grzywacz、Stanisław Marczak、Jerzy Wicha
    DOI:10.1021/jo9705834
    日期:1997.8.1
    Vitamin D-3 hydrindan ring-side-chain building block 4 (racemic) has been synthesized from ketene acetal 12 (derived from 6-methylheptanoic acid), 2-methylcyclopent-2-en-1-one (13), allyl methyl carbonate, and dimethyl methylphosphonate. The Mukaiyama-Michael conjugate addition of 12 and 13 yielded the adduct 11 (lk) accompanied by ca. 10% of its diastereomer. Allylation of 11 with allyl methyl carbonate in the presence of palladium catalyst afforded 10. The latter was transformed into enol lactone 26, which on treatment with 2 equiv of lithium dimethyl methylphosphonate and then 1 equiv of acetic acid provided 4.
  • Total Synthesis of <i>e</i><i>nt</i>-Cholesterol via a Steroid C,D-Ring Side-Chain Synthon
    作者:Xin Jiang、Douglas F. Covey
    DOI:10.1021/jo025535k
    日期:2002.7.1
    7a-hexahydro-7a-methyl-5H-inden-5-one, C,D ring-side chain synthons that can be used for the synthesis of enantiomers of vitamin D(3), cholesterol, and their analogues was also developed. Using the enantiomer of the C,D-ring side-chain synthon that leads to ent-cholesterol, the A- and B-rings were elaborated from a linear fragment that is sequentially cyclized to form the steroid B- and A-rings. Using
