  • Diiodosamarium, a unique catalyst precursor for ene reactions of unsaturated carbonyl compounds
    作者:Tarun K. Sarkar、Sandip K. Nandy

  • Stereochemical Control over Three Contiguous Stereogenic Centers in the Intramolecular Ene Reaction of Activated 1,6-Dienes. Application to the Synthesis of (±)-Methyl Cucurbate and (±)-Methyl Epijasmonate
    作者:Tarun K. Sarkar、Binay K. Ghorai、Sandip K. Nandy、Bireswar Mukherjee、Asoke Banerji
    DOI:10.1021/jo961739n
    日期:1997.8.1
    The influence of a protected alcohol group adjacent to the ene or enophile component on diastereoselectivity in both thermal and Lewis acid-catalyzed 5-(3,4) ene reactions of a series of 1,6-dienes 1-7 has been studied. The results indicate that its effect can be considerable, and in one example, with a gem-dimethyl group on the connecting chain and a large silyl protecting group on the hydroxyl, the diastereocontrol was almost perfect, with three stereogenic centers and one double bond geometry set up in one step, e.g., 4 --> 10. This new finding was exploited in a synthesis of epijasmonoid natural products, (+/-)-methyl cucurbate (19) and (+/-)-methyl epijasmonate (18) starting from aldehyde 24, where the key step was a highly diastereocontrolled 5-(3,4) ene cyclization 23 --> 22.

  • Intramolecular Alder ene reaction of activated 1,6-dienes : Stereochemical control over three contiguous stereogenic centres
    作者:Tarun K. Sarkar、Binay K. Ghoral、Sandip K. Nandy、Bireswar Mukherjee
    DOI:10.1016/0040-4039(94)85037-2
    日期:1994.9
    An intramolecular ene approach to stereocontrol over contiguous stereogenic centres is described, where three centres can be created with very high level of both diastereofacial selectivity and diastereoselectivity by the influence of an oxygen substituent as a stereodirecting resident group in the ene component.
    描述了一种分子内烯对连续的立体发生中心进行立体控制的方法,其中可以通过作为烯组分中的立体定向驻留基团的氧取代基的影响而产生具有非常高水平的非对映选择性和非对映选择性的三个中心。
