  N,O-Nucleosides from Ene Reactions of Nitrosocarbonyl Intermediates with the 3-Methyl-2-buten-1-ol

  摘要：

  Nitrosocarbonyl intermediates undergo ene reactions with allylic alcohols, affording regioisomeric adducts in fair yields. Nitrosocarbonyl benzene reacts with 3-methyl-2-buten-1-ol and follows a Markovnikov orientation and abstracts preferentially the twix hydrogens over the lone ones. With the more sterically demanding nitrosocarbonyl mesitylene and anthracene, the Markovnikov directing effect is relieved and lone abstraction is observed, affording the 5-hydroxy-isoxazolidines that serve as synthons for the preparation of N,O-nucleoside analogues according to the Vorbruggen protocol.

  choice for the preparation of N,O-nucleoside analogues containing purine rings by means of the Vorbrüggen protocol. Sterically encumbered nitrosocarbonyl derivatives of mesitylene or anthracene undergo ene reactions with 3-methylbut-2-en-1-ol to give the corresponding the 5-hydroxyisoxazolidine adducts in fair yields. According to the proposed mechanism, these heterocycles are derived from the anti-Markovnikov

  摘要 立体上受到干扰的1，3，5-三甲基苯或蒽的亚硝基羰基衍生物与3-甲基丁-2-烯-1-醇进行烯反应，以适当的收率得到相应的5-羟基异恶唑烷加合物。根据所提出的机理，这些杂环是从烯反应的反马尔科夫尼科夫方向衍生的。乙酸异恶唑烷-5-基酯衍生物是通过Vorbrüggen方案制备含嘌呤环的N，O-核苷类似物的首选合成子。 立体上受到干扰的1，3，5-三甲基苯或蒽的亚硝基羰基衍生物与3-甲基丁-2-烯-1-醇进行烯反应，以适当的收率得到相应的5-羟基异恶唑烷加合物。根据所提出的机理，这些杂环是从烯反应的反马尔科夫尼科夫方向衍生的。乙酸异恶唑烷-5-基酯衍生物是通过Vorbrüggen方案制备含嘌呤环的N，O-核苷类似物的首选合成子。
