Description of 1,2-O-Isopropylidene-α-D-Xylofuranose (CAS No. 20031-21-4)
1,2-O-Isopropylidene-α-D-xylofuranose can act as a starting material for producing 3-deoxy-1,2-O-isopropylidene-D-xylofuranose. This product functions as a chiral building block for constructing the pharmacologically active side chain of atorvastatin, and also serves a vital role in the synthesis of many other pharmaceutical intermediates.
