  Synthesis of the Adrenergic Bronchodilators (R)-Terbutaline and (R)-Salbutamol from (R)-Cyanohydrins¹

  摘要：

  Stereoselective syntheses of (R)-terbutaline and (R)-salbutamol acetal, which are important bronchodilators, starting from O-protected (R)-cyanohydrins are described. (R)-Terbutaline hydrochloride (R)-9.HCl is obtained in an overall yield of 44% with >98% ee from the O-bisallyl-protected cyanohydrin (R)-4k via a Ritter N-tertiary butylation to the amide (R)-6a, hydrogenation to the amino alcohol (R)-7a, and deprotection of the hydroxyl functions. (R)-Salbutamol acetals (R)-7b,c can be obtained from the corresponding O-protected (R)-cyanohydrins either via the route described for (R)-terbutaline or via selective hydrogenation of the protected cyanohydrin (R)-11 to the imino derivative, transimination with tert-butylamine, followed by hydrogenation with NaBH4 to give the 2-amino alcohol derivative (R)-12. Desilylation of(R)-12 to (R)-7c is performed with LiAlH4. Hydrolytic cleavage of the acetals (R)-7b and c to (R)-salbutamol was not yet possible without racemization.

  groups has been achieved successfully with the reaction of allyl bromide by using sodium perborate as a new catalyst in aqueous media. The advantage of this method is operationally simple, short reaction time, good yield, and simple workup conditions over the previously reported conventional methods such as amination, oxyalkylation reactions of allyl bromide, and Friedel–Crafts allylation chemistry.
