  Intramolecular addition of carbon radicals to aldehydes: synthesis of enantiopure tetrahydrofuran-3-ols

  摘要：

  A simple and efficient substrate-controlled asymmetric synthesis of enantiopure tetrahydrofuran-3-ols by a 5-exo-trig radical cyclization is described. This cyclization occurs when a delta-carbon radical adds intramolecularly to the carbonyl group of an aldehyde. The delta-carbon radicals can be efficiently produced from the tin hydride mediated deselenenylation of 5-phenylseleno-3-oxapentanals, which were easily prepared starting from commercially available enantiopure epoxides or chlorohydrins.

• Ring-Closure Reactions through Intramolecular Displacement of the Phenylselenonyl Group by Nitrogen Nucleophiles: A New Stereospecific Synthesis ofN-Tosyl andN-Benzoyl-1,3-oxazolidin-2-ones fromβ-Hydroxyalkyl Phenyl Selenides

  3-oxazolidin-2-ones from the easily available beta-hydroxyalkyl phenyl selenides is presented. After transformation into the N-tosyl or N-benzoyl carbamates, the selenides were oxidized to the corresponding selenones. The key step of the process is the ring-closure reaction, which occurs by stereospecific intramolecular nucleophilic substitution of the selenone group by the nitrogen atom of the carbamate. Enantiomerically

  提出了一种新的方便的方法，用于从容易获得的β-羟烷基苯基硒化物立体定向合成各种取代的1,3-恶唑烷-2-酮。在转变成N-甲苯磺酰基或N-苯甲酰基氨基甲酸酯之后，硒化物被氧化成相应的硒酮。该过程的关键步骤是闭环反应，该反应是通过氨基甲酸酯的氮原子对硒酮基团进行立体特异性分子内亲核取代而发生的。通过使用对映体纯的β-羟烷基苯基硒化物作为起始原料，可以容易地制备对映体纯的1，3-恶唑烷-2-酮衍生物。

  pure epoxides, enantiomerically pure substituted tetrahydrofurans were prepared using simple conversions promoted by organoselenium reagents. The first step consisted in the opening of the epoxides with phenylselenolate anions to afford hydroxyalkyl phenyl selenides. The PhSe group was then substituted by an allyl group by treatment with allyltributyltin and AIBN. The reaction of these allylic derivatives

  Eleven beta-hydroxy selenides were kinetically resolved using an immobilized lipase (Amano PS-C II) in toluene in the presence of vinyl acetate at 30 degrees C. This approach provided, in several cases, both enantiomers in high enantiomeric excess. The role of the size of substituents and the behaviour of cyclic beta-hydroxy selenides is also discussed. Enantiopure beta-hydroxy selenides are useful building blocks. As an application of this chemistry, enantiopure (1S,2R)-indene oxide was obtained in one step from the proper enantiopure beta-hydroxy selenide. (c) 2006 Published by Elsevier Ltd.
