Construction of a bicyclic beta-benzyloxy and beta-hydroxy amide library through a multicomponent cyclization reaction

J Comb Chem. Jul-Aug 2009;11(4):640-4. doi: 10.1021/cc800200h.


In this manuscript, we describe the synthesis of a bicyclic beta-benzyloxy and beta-hydroxy amide library from cyanohydrin ethers. The benzyloxy amides were prepared through a one-pot sequence of hydrozirconation, acylation, and intramolecular Friedel-Crafts alkylation. Selected benzyl ethers were converted to alcohols by hydrogenolysis in a continuous flow reactor. Chemistry space BCUT metrics and 2D fingerprint similarity calculations showed that these compounds contribute chemical diversity value to existing chemical libraries.
