抄録

The reaction of methyl 2,3-anhydro-α-<FONT SIZE=-2>D</FONT>-ribofuranoside or methyl 2,3-anhydro-5,6-<I>O</I>-cyclohexylidene-α-<FONT SIZE=-2>D</FONT>-allofuranoside with 2-propynyl metallic reagents exclusively gave the corresponding 2-<I>C</I>-(2-propynyl)-<I>arabino</I>-pentofuranosides and 2-<I>C</I>-(2-propynyl)-<I>altro</I>-hexofuranosides, respectively. In contrast, the β-anomers were selectively attacked at the position 3 to afford the corresponding 3-<I>C</I>-(2-propynyl)furanosides.
