Lithium diisopropylamide undergoes an addition reaction to the methyleneamino moiety of the title Schiffs bases substituted with a cyano group at the ortho or parn position of the aniline, but mediates tautomerization of the unsubstituted and metasubstituted derivatives into secondary enamines. Onl
Reaction of various para-substituted tj-(a-methoxyphenacyl)anilines with lithioisobutyrate in excess gives,in good yield, compounds 2-6 through -a regiocontrolled process. In a previous paper', we have reported the synthesis and reactions of some novel substituted B-hydroxy-y-imino esters which can
