dc.description.abstract2-Alkylaminophenylprop-1-yn-3-ols, prepared from the lithium diisopropylamide (LDA)-mediated 1,2-addition of alkynes to 1-(2-aminophenyl) ketones, can be converted to 3,3-disubstituted 2-oxindoles by using silica gel in n-hexane/ethyl acetate (20:1 v/v) as the reaction medium. The utility of the approach as a potential scale-up strategy for the synthesis of 2-oxindoles was exemplified by the large-scale synthesis of one adduct in excellent yield. The synthetic applicability of this chemistry was also demonstrated by the recycling of the silica gel up to 8 times with no apparent loss of activity being observed for the same example.en_US
