The partial reduction of a series of heterocycles in THF is described. By adding amine 3 as a proton source and naphthalene as an electron carrier, we were able to produce reductively alkylated pyrrolines and dihydrofurans in moderate to good yields. This reaction does not require liquid ammonia as a solvent, which may have interesting ramifications for large-scale synthesis. Moreover, we were also able to quench the reduction reactions with an acid chloride so performing a reductive acylation reaction. (C) 2000 Elsevier Science Ltd. All rights reserved.
