  • Addition of N-benzylhydrazine to sugar δ-enlactones
    作者:I Panfil、J Krajewski、P Gluziński、L Stefaniak、M Chmielewski
    DOI:10.1016/s0040-4020(01)85245-5
    日期:1994.1
    rearrangement of N-benzylhydrazine to sugar δ-enlactone with erythro configuration 1 and 2 affords mixtures of respective ribo and arabino isomers with the former one prevailing. In the case of the threo lactone 3 two regioisomers with xylo configuration are produced, whereas in the case of 4 only one isomer with the erythro configuration is formed. The stereochemical course of these rections was explained
    共轭加成-将N-苄基肼重排为具有赤型构型1和2的糖δ-内酯,得到各自的核糖和阿拉伯糖异构体的混合物,其中前一种占优势。在苏式内酯3的情况下,产生了两个具有木糖构型的区域异构体,而在4的情况下,仅形成了一个具有赤型构型的异构体。解释了这些反应的立体化学过程。
  • Stereoselective syntheses and reactions of chiral oxygenated α,β-unsaturated-γ- and δ-lactones
    作者:Francisco Sánchez-Sancho、Serafín Valverde、Bernardo Herradón
    DOI:10.1016/0957-4166(96)00424-7
    日期:1996.11
    The syntheses of the chiral α,β-unsaturated lactones (+)-5, (−)-6, (+)-8, (+)-9, and (+)-10 have been efficiently achieved from readily available starting materials. The lactone (+)-5 has been synthesized in 7 steps from (R,R)-dimethyl tartrate (38–43% overall yield). The use of (+)-5 in formal syntheses of natural (+)-asperlin 4 and advanced intermediates for (+)-olguine 2 are also reported. The lactone
    手性α,β-不饱和内酯(+)- 5,(-)- 6,(+)- 8,(+)- 9和(+)- 10的合成已从容易获得的起始原料中高效地获得。内酯(+)- 5已由(R,R)-酒石酸二甲酯(7-43%的总产率)分7个步骤合成。还报道了在天然(+)-asperlin 4和(+)-olguine 2的高级中间体的正式合成中使用(+)- 5。内酯(-)- 6已从(R-苹果酸(总收率44-50%)。对于分支链和脱氧核苷类似物的合成,它可能是有用的前体。(-)- 6的制备构成了天然(+)-艾加醇化物53和(+)-Geissman-Waiss内酯54(用于合成多种吡咯烷核生物碱的中间体)的形式合成。内酯(+)- 8,(+)- 9和(+)- 10已由3,4-二-O-乙酰基-L-鼠李糖醇58合成。(+)- 9和(+)- 10的高度非对映选择性转化,通过顺序的共轭亲核加成和烯醇酸酯反应,转变为致密官能化的手性γ-内酯还报告了12个。
  • Biomimetic Total Synthesis of Angiopterlactone B and Other Potential Natural Products
    作者:Tharun K. Kotammagari、Rajesh G. Gonnade、Asish K. Bhattacharya
    DOI:10.1021/acs.orglett.7b01525
    日期:2017.7.7
    A one-pot biomimetic synthesis of (−)-angiopterlactone B and its enantiomer (+)-angiopterlactone B has been accomplished via TBAF-catalyzed tandem ring contraction followed by oxa-Michael/Michael addition sequence. Comparison of specific optical rotations, absolute configurations, and CD spectra of natural, synthesized (−)-angiopterlactone B and (+)-angiopterlactone B unequivocally proves that the
    已经通过TBAF催化的串联环收缩和oxa-Michael / Michael加成序列完成了一锅仿生合成(-)-angiopterlactone B和其对映异构体(+)-angiopterlactone B的过程。比较天然,合成的(-)-血管内酯B和(+)-血管内酯B的比旋光度,绝对构型和CD光谱,可以明确地证明分离出的血管内酯B必须是左旋的。迄今未发现的天然产物18和20以及血管内酯B的类似物的合成证明了该方法的多功能性。
  • The Reaction of (4R,5R)- and (4S,5S)-4,5-Epoxy-2(E)-Hexenoates and Secondary Amines.
    作者:Chikako SAOTOME、Machiko ONO、Hiroyuki AKITA
    DOI:10.1248/cpb.49.849
    日期:——
    A reaction of methyl (4R,5R)-4,5-epoxy-2(E)-hexenoate 1 with N-benzylmethylamine gave a diastereomerically pure methyl (4R,5R)-4,5-epoxy-(3S)-N-benzylmethylamino hexanoate 6 and methyl (4S,5R)-4-N-benzyl-methylamino-5-hydroxy-2(E)-hexenoate 7. The former was chemoenzymatically converted to (-)-osmundalactone 11, which is an aglycone of osmundalin. On the other hand, the directly conjugated addition
    (4R,5R)-4,5-环氧-2(E)-己酸甲酯1与N-苄基甲胺的反应得到非对映异构纯的甲基(4R,5R)-4,5-环氧-(3S)-N-苄基甲基氨基己酸酯6和(4S,5R)-4-N-苄基-甲基氨基-5-羟基-2(E)-己烯酸酯7。前者经化学酶法转化为(-)-osmundalactone 11,后者是osmundalin的苷元。 。另一方面,将二甲胺直接共轭加成到(4S,5S)-4,5-环氧-2(E)-己酸甲酯1中,然后在40℃下用MeOH处理,独家提供甲基(4R,5S)- 4-二甲基氨基-5-羟基-2(E)-己酸酸酯16,将其转化为L-(-)-山os糖18。

    作者:Pan Jarglis、Frieder W Lichtenthaler
    DOI:10.1016/s0040-4039(00)87705-9
    日期:1982.1
    An effective, one-step procedure for conversion of glycal and 2-acyloxyglycal esters to 2,3-unsaturated lactones has been developed, involving BF3-induced removal of the allylic acyloxy function and oxidation with m-chloroperbenzoic acid or pyridinium chlorochromate.
    已经开发出一种有效的一步法,将糖基和2-酰氧基糖基酯转化为2,3-不饱和内酯,包括BF 3诱导的烯丙基酰氧基官能团的去除和间氯过苯甲酸或氯代吡啶鎓铬酸盐的氧化。
