    碘(III)介导的3,4-二氢吡喃酮的收缩:获得多取代的γ-丁内酯
    摘要:
    功能化的γ-丁内酯是药物化学领域中的优先结构。它们存在于多种具有多种生物活性的天然产物和合成化合物中。3,4-二氢吡喃-2-酮衍生物的氧化环收缩代表了一种有前途但未被充分认识的接近这些化合物的策略。据我们所知,几乎没有报道过这种策略的例子,对立体异构中心对起始二氢吡喃酮的影响的研究还很有限。我们调查了碘(III)介导的一组二氢吡喃酮衍生物的收缩。该方法可快速获得高产率的功能化γ-丁内酯。研究了反应范围,发现该方法可支持各种水平的取代基,甚至可以访问拥挤的四元中心。使用手性底物和手性碘(III)试剂研究了立体选择性。

    Ring Closure Reactions of Substituted 4-Pentenyl-1-oxy Radicals. The Stereoselective Synthesis of Functionalized Disubstituted Tetrahydrofurans
    摘要:
    N-(Alkyloxy)pyridine-2( VT)-thiones 3 and benzenesulfenic acid O-esters 5 have been synthesized from substituted 4-pentenols 1 or the derived tosylates. Compounds 3 and 5 are efficient sources of free alkoxy radicals 6 which undergo synthetically useful fast ring closure reactions 6 --> 8 [k(exo) = (2 +/- 1) x 10(8) s(-1) to (6 +/- 2) x 10(9) s(-1) (T = 30 +/- 0.2 degrees C)]. Tetrahydrofurfuryl radicals 8 can be trapped with, e.g., hydrogen or chlorine atom donors to afford either trans- or cis-disubstituted tetrahydrofurans 10 or 12 depending on the substitution pattern of the 4-pentenyloxy radical. Substituted tetrahydropyrans 11 or 13 are formed in the minor 6-endo-trig cyclization. According to the data of competition kinetics, the observed stereoselectivities in free alkoxy radical cyclizations arise from steric interactions between the substituents in the transition state of the ring closure reactions. Alkyl substituents cause small differences in the measured relative rate constants of B-exo cyclizations which are reminiscent of the data obtained from the rearrangements of alkyl-substituted 5-hexenyl radicals. Likewise, a stereochemical model for oxygen radical cyclization is proposed where the pentenyloxy chain adopts a six-membered, chairlike transition state with the alkyl substituents preferentially situated in the pseudoequatorial positions leading to 2,5-trans-, 2,4-cis-, and 2,3-trans-substituted tetrahydrofurfuryl radicals 8 as the major intermediates.
