  Tuning Stereoselection in Tethered Biginelli Condensations. Synthesis of cis- or trans-1-Oxo- and 1-Iminohexahydropyrrolo[1,2-c]pyrimidines

  摘要：

  Stereoselection in tethered Biginelli condensations can be tuned to give either the cia or trans stereoisomer of 1-oxohexahydropyrrolo[1,2-c]pyrimidine and 1-iminohexahydropyrrolo[1,2-c]pyrimidine products (see eq 1). With substrates having urea and N-sulfonylguanidine functionality (Schemes 2 and 4), cis stereoselection (4-7:1) is observed when the condensation is accomplished under Knoevenagel conditions, while trans stereoselection (4-20:1) is observed when the condensation is carried out in the presence of polyphosphate ester (PPE). Under both conditions, steroselectivity is highest in the N-sulfonylguanidine series. With substrates bearing a basic guanidine unit, the trans product is formed exclusively under Knoevenagel conditions (Scheme 3).

• Synthesis of Cyclic Guanidines Bearing <i>N</i>-Arylsulfonyl and <i>N</i>-Cyano Protecting Groups via Pd-Catalyzed Alkene Carboamination Reactions
  作者：Luke J. Peterson、Jingyi Luo、John P. Wolfe

  DOI：10.1021/acs.orglett.7b00946

  日期：2017.6.2

  Palladium-catalyzed carboamination reactions of N-allylguanidines bearing cleavable N-cyano or N-arylsulfonyl protecting groups are described. The reactions afford cyclic guanidine products in good yield, and transformations of substrates bearing internal alkenes proceed with high diastereoselectivity. Deuterium labeling studies indicate these transformations proceed via anti-aminopalladation pathways
