efficient, stereoselective and short approach for the total syntheses of some carbahexopyranoses namely, MK7607, (−)-gabosine A, (−)-conduritol E, (−)-conduritol F, 6a-carba-β-D-fructopyranose and other carbasugars using chemoselective Grignard or Nozaki–Hiyama–Takai–Kishi (NHTK) reactions and RCM. Herein, the Grignard and NHTK reactions are able to differentiate the reactivity difference between lactol
一种通用、发散、高效、立体选择性和简短的方法,用于全合成某些吡喃碳糖,即 MK7607、(−)-gabosine A、(−)-conduritol E、(−)-conduritol F、6a-carba-β- D -吡喃果糖和其他卡巴糖,使用化学选择性格氏反应或野崎-桧山-高井-岸 (NHTK) 反应和 RCM。在此,格氏反应和NHTK反应能够在给定条件下区分乳醇或乳醇乙酸酯与醛2和6之间的反应性差异,以给出所需的骨架化学选择性。
