PG - 39061-39070 LID - 10.1021/acsomega.2c04804 [doi] AB - A method to obtain tetrahydroisoquinolines (THIQs) fused to tetrahydrofuran rings from aminosugar derivatives has been developed. The procedure relies on a key deprotection of benzyl ethers followed by a double-cyclization sequence, using FeCl(3) as the sole reagent. This tandem reaction affords the construction of novel fused polycyclic heterocycles with total stereochemical control. CI - (c) 2022 The Authors. Published by American Chemical Society.
