  Enantiospecific Total Synthesis of l-2‘,3‘-Dideoxyisonucleosides via Regioselective Opening of Optically Active C₂-Symmetric 1,4-Pentadiene Bis-epoxide¹

  摘要：

  A new method for the synthesis of L-2',3'-dideoxyisonucleosides is described. The readily available, optically active C-2-symmetric bis-epoxide (2S,4S)-1,2:4,5-diepoxypentane (5) was prepared by a short route from readily available starting materials. The key step of the new synthesis is the opening of 5 with nucleophiles, which proceeds highly regioselectively; e.g., reaction with sodium sulfide affords a 5:1 mixture of the tetrahydrothiophenediol 9a and the tetrahydrothiopyrandiol 14, and reaction with sodium hydroxide gives exclusively the tetrahydrofurandiol 9b via a preferred 5-exo cyclization. These five-membered diols 9a,b can be converted in only four steps into the modified dideoxyuridine and adenosine isonucleosides 4a-c, one of which (4c) has shown good antiviral activity. In addition, we have examined the opening of the analogous six carbon bis-epoxide, (2S,5S)-1,2:5,6-diepoxyhexane (23), which affords a 3:1 mixture of the hexahydrothiepinediol 24 and the tetrahydrothiopyrandiol 25 with sodium sulfide via a preferred 7-endo cyclization. An alternate route to these two optically active bis-epoxides 5 and 23 was also examined, namely the asymmetric dihydroxylation of 1,4-pentadiene and 1,5-hexadiene followed by selective sulfonylation and epoxide : formation. The asymmetric reaction produces a nearly 1:1 mixture of optically active and meso tetrols, e.g., 28-9 and 32-3. Unfortunately, the tetrols, their simple derivatives, and the final sulfonates and epoxides could not be readily separated by Rnv simple means.

  A highly convergent synthesis of the macrolide natural product milbemycin β1 is reported. The key features of this synthesis include the introduction of the C11-C15 side chain by selective ring opening of a symmetrical 1,4-pentane bis-epoxide (3) followed by reaction with the anion derived from the 2,3-trans-dimethyl-6-phenylsulphonyl pyran (2) to afford the “northern” C11-C25 fragment (33) of milbemycin

  phenyl 4,4'-bis(oxazoline) [AraBOX] is described. The novel ligand is prepared in two efficient steps from a bis-[(O-silyl)β-amino alcohol], via conversion into an intermediate bis(benzamide) followed by a one-pot deprotection-activation-ring closure (DARC) oxazoline formation. To our knowledge, this is the first reported synthesis of an oxazoline ring via this DARC method. The synthesis of two precursor

  Two endogenous γ-lactones, 3-hydroxy-4-butanolide (1) and 2-hydroxy-4-hydroxymethyl-4-butanolide (2) have been identified as substances that enhance, respectively, satiety and hunger by their effects on the feeding behavior and the central neurons of rats. To determine the stereochemistry of the physiologically active isomers, all the stereoisomers of these two lactones were synthesized and their effects on the feeding behavior and humoral factors were assessed by infusion into the rat third cerebroventricle. Among four isomers, (2S,4S)-2-hydroxy-4-hydroxymethyl-4-butanolide (2a) was most effective in elicitating the feeding and caused potent hypoglycemia with hyperinsulinemia. (S)-3-Hydroxy-4-butanolide (1a) suppressed the food intake more potently than the antipode and caused humoral responses reciprocal to those of 2a. From these facts, it was concluded that 1a and 2a are physiologically active forms for conveying intrinsic signals of satiety and hunger to neurons in the hypothalamus.

  两种内源性γ-内酯--3-羟基-4-丁内酯（1）和 2-羟基-4-羟甲基-4-丁内酯（2）已被确认为可通过影响大鼠的摄食行为和中枢神经元而分别增强饱腹感和饥饿感的物质。为了确定具有生理活性的异构体的立体化学结构，我们合成了这两种内酯的所有立体异构体，并通过将它们注入大鼠第三脑室来评估它们对摄食行为和体液因素的影响。在四种异构体中，(2S,4S)-2-羟基-4-羟甲基-4-丁内酯（2a）诱导摄食的效果最好，并能引起强效低血糖和高胰岛素血症。(S)-3-羟基-4-丁醇内酯（1a）对食物摄入的抑制作用比反式内酯更强，引起的体液反应与 2a 类似。由此得出结论，1a 和 2a 是向下丘脑神经元传递饱腹感和饥饿感内在信号的生理活性形式。
