Synthetic studies toward the preparation of (4R,5R)-(−)-3-[(benzyloxy)methyl]-4,5-O-isopropylidene-cyclopenten-2-one: an important synthetic intermediate for carbanucleosides
摘要:
The carbocyclic compound (4R,5R)-(-)-3-[(benzyloxy)methyl]-4,5-O-isopropylidene-2-cyclopentenone 1 is an important synthetic intermediate to access a variety of carbanucleosides. Herein, synthetic studies that lead to this valuable compound employing inexpensive D-ribose as the chiral source are presented. (C) 2004 Elsevier Ltd. All rights reserved.
