05 - 043Photodecarboxylative Additions of α-Keto Carboxylates to Phthalim-ides. Alkylation, Acylation, and Ring Expansion. — The substitutionpattern of α-keto carboxylates shows a strong influence on their reactivityin the photodecarboxylative addition to N-methyl phthalimide.Secondary ortertiary α-keto carboxylates (I) give the alkylation products (III), glyoxylate thereduction product (IV). The primary educts (V) and (VII) yield ring expansionproducts and the acylation product (IX). — (GRIESBECK, AXEL G.;OELGEMOELLER, MICHAEL; LEX, JOHANN; Synlett (2000) 10, 1455-1457;Inst. Org.
