Abstract

A high-yielding five-step synthesis of cis-benzofuropyridin-6-ols provided an improved route to compounds with low to subnanomolar affinity at opioid receptors and high antinociceptive potency. This synthesis provided the known rac-cis-4a-ethyl-2-methyl-1,2,3,4,4a,9a-hexahydrobenzofuro[2,3-c]pyridin-6-ol (1a) in high yield, and the novel rac-cis-2-methyl-4a-phenethyl-1,2,3,4,4a,9a-hexahydrobenzofuro[2,3-c]pyridin-6-ol (1b). It was achieved using NBS to prepare the key intermediate 7. Di-demethylation followed by subsequent displacement of the bromine by the phenolic ion in hot Et(3)N gave the desired 1a. The structure of 1a was confirmed by X-ray crystallography.
