Different types of unsaturated sugars
have been synthesized from such readily available substrates [5,10]. The older methods, still
used with great success in the synthesis of complex modified unsaturated carbohydrates,
may be found in an excellent review by Ferrier [11]. For the newer ones see the recent
reviews [1,2,4,6].
