New method for the synthesis of alpha-substituted tetrahydrofuran-2-methanols through diastereoselective addition of THF to aldehydes mediated by Et3B in the presence of air
T. Yoshimitsu et al., New method for the synthesis of alpha-substituted tetrahydrofuran-2-methanols through diastereoselective addition of THF to aldehydes mediated by Et3B in the presence of air, CHEM COMMUN, (17), 1999, pp. 1745-1746
The tetrahydrofuranyl radical, generated from THF with Et3B in the presence
of air, was found to react with aldehydes threo-selectively to afford alph
a-substituted tetrahydrofuran-2-methanols, the common structural motifs of
biologically active acetogenin polyketides, in moderate yields.
