The β1-adrenergic antagonist (S,R,R,R)-α,α′-iminobis(methylene)bis(6-fluoro-3H,4H-dihydro-2H-1-benzopyran-2-methanol) was synthesized from natural chiral pool starting materials through an efficient, convergent synthetic strategy. The cyclization mechanism of the key step was investigated using computer modeling and is discussed.
从天然手性池起始原料出发,通过一种高效、汇聚性的合成策略,合成了β1-肾上腺素能拮抗剂(S,R,R,R)-α,α'-亚氨双(亚甲基)双(6-氟-3H,4H-二氢-2H-1-苯并吡喃-2-甲醇)。借助计算机建模研究了关键步骤的环化机理,并进行了讨论。
