The formal synthesis of chiral etodolac using chiral 1,2- di(alkylcarbonyl)oxypentan-3-one as chiral building block

A stereoselective synthesis of (+)- and (-)-(1,8-diethyl-1,3,4,9- tetrahydropyrano[3,4-b]indol-1-yl)-1-ethanois (31) and (32), the key intermediates for chiral etodolac was executed in seven steps starting from the asymmetric cyclization of (2R)-1,2-di(ac
