Abstract
The reduction of aryl and alkenyl methyl ketones using lithium aluminu m hydride modified with ,2S,3S,5R)-(+)-10-anilino-3-ethoxy-2-hydroxypi nane (3), afforded chiral secondary alcohols in 83-96% yields and 53-9 7% optical yields. The modifier 3 was prepared from (1R)-(-)-myrtenol and was readily recovered (>96%) after reduction. The reduction of ace tophenone in the presence of lithium iodide gave the alcohol product w ith higher optical yield.
