  Asymmetric Organocatalytic Monofluorovinylations

  摘要：

  The development of highly enantio- and c organocatalytic monofluorovinylations is presented. Based on the application of alpha-fluoro beta-keto-benzothiazolesulfones, the formal addition of a monofluorovinylic anion synthon to a range of acydic and cyclic enones, as well as imines, is shown. These procedures give selective access to both E- and Z-isomers of the monofluorovinylated products, which are isolated as the pure diastereoisomers in good to excellent yields with up to 99% ee. Furthermore, the application of this concept for the formation of highly enantioenriched bicylic compounds containing a monofluorovinyl moiety is also described. In addition, a mechanistic rationale for the observed E:Z-selectivities is presented.

  高化学/立体选择性合成多取代的单氟嘧啶烯醇醚衍生物

  摘要：

  开发了新型的α-氟-β-酮-嘧啶基砜的分子内Smiles重排（通常用作碳亲核试剂），为合成三/四取代的单氟嘧啶基烯醇醚提供了多方面的途径。其中，通过添加额外的亲电试剂和微调反应条件，可以有效地组装各种（Z）-单氟乙烯基砜和亚磺酸盐。从烯醇氧阴离子到嘧啶2-碳的酮-烯醇互变异构现象触发了这一过程，这与经典的碳亲核加成反应方法完全不同。

  Synthesis and reactivity of N-methoxy-N-methyl-(1,3-benzothiazol-2-ylsulfonyl)fluoroacetamide, a building block for Julia olefination, is reported. This reagent undergoes condensation reactions with aldehydes and cyclic ketones to give alpha-fluorovinyl Weinreb amides. Olefination reactions proceed under mild, DBU-mediated conditions, or in the presence of NaH. DBU-mediated condensations proceed with either E- or Z-selectivity, depending upon reaction conditions, whereas NaH-mediated reactions are >= 98% Z-stereoselective. Conversion of the Weinreb amide moiety in N-methoxy-N-methyl-(1,3-benzothiazol-2-ylsulfanyl)fluoroacetamide to ketones, followed by oxidation, resulted in another set of olefination reagents, namely (1,3-benzothiazol-2-ylsulfonyl)fluoromethyl phenyl and propyl ketones. In the presence of DBU, these compounds react with aldehydes tested to give alpha-fluoroenones with high Z-selectivity. The use of N-methoxy-N-methyl-(1,3-benzothiazol-2-ylsulfanyl)fluoroacetamide as a common fluorinated intermediate in the synthesis of alpha-fluorovinyl Weinreb amides and alpha-fluoroenones has been demonstrated. Application of the Weinreb amide to alpha-flu-fluoro allyl amine synthesis is also shown.

  A novel intramolecular Smiles rearrangement of α-fluoro-β-keto-pyrimidylsulfones (usually used as a carbon nucleophile) was developed, providing a versatile avenue for synthesis of tri/tetra-substituted monofluorinated pyrimidyl enol ethers. Among these, diverse (Z)-monofluorovinylsulfones and sulfinates were efficiently assembled by adding extra electrophile and fine-tuning reaction conditions. The
