2-Deoxy-L-ribose may be prepared by reacting a compound represented by formula (1) with an organometallic compound represented by formula (2) to give a compound represented by formula (3), which is then subjected to deprotection of a hydroxyl group and production of aldehyde by acid hydrolysis:
wherein R
1
and R
2
are each independently a hydroxyl-protecting group or R
1
and R
2
in combination form a hydroxyl-protecting group, R
3
and R
4
are each independently an alkyl group, an aralkyl group, an aryl group or a silyl group or R
3
and R
4
in combination form an alkylene group.
