โฆ Synopsis
Some chiral acetals are cleaved by organoaluminum reagents. The products are formed diastereoselectively, and the removal of the chiral auxiliary affords optically active alcohols. A recent communication by Bartlett, Johnson and Elliott1 on the acetal derived from (-)-(2$4_R)-2,4-pentanediol has prompted us to report our own efforts in this area.
