✦ Synopsis
Good yields of 2-dialkylamincmethylfurans are obtained when N,N-dialkylmethyleneimonium chlorides are allowed to interact with furan in acetonitrile at room temperature; similar results are obtained using 2-methylfuran.
Mannich reactions I of 2-methylfuran have been reported to afford good yields of 2-N,N-dialkyaminomethyl-5-methylfuran using aqueous formaldehyde and secondary amines under
