Jiro Tsuji (May 11, 1927 – April 1, 2022)[1] was a Japanese chemist, notable for his discovery of organometallic reactions, including the Tsuji-Trost reaction, the Tsuji-Wilkinson decarbonylation, and the Tsuji-Wacker reaction.

Early life and education[edit]

Tsuji was born in Japan in 1927.[1]

After attending Kyoto University, Tsuji began his doctoral research at Columbia University under Gilbert Stork[2] studying natural product synthesis, and making contributions to research on the dissolving metal reduction of enones.[3][4]

Independent career[edit]

His independent career began at Toyo Rayon (now Toray Industries) studying the stoichiometric, and later catalytic[5] carbonylation of PdII-alkene complexes with carbon monoxide.[6][7] His preliminary results showed that acyl halides and aldehydes could be decarbonylated by Pd0 at high temperatures (200 °C) yielding alkenes;[8] further investigation revealed that stoichiometric quantities of Wilkinson's catalyst was able to affect the same reaction at lower temperatures,[9] now known as the Tsuji-Wilkinson decarbonylation.

Tsuji's first report of rhodium-mediated decarbonylation.[9]

His pioneering work resulting in the development of the Tsuji-Trost reaction was the discovery that allyl-PdII complexes react with malonates, acetoacetates, and enamines yielding alpha-allylated carbonyl compounds,[10] which was later generalized and rendered asymmetric by Barry Trost.[11] Tsuji additionally noted the utility of these alpha-allylated ketones and esters in preparing 1,4-dicarbonyl compounds using the Wacker oxidation.[12]

Tsuji's first report of palladium-mediated allylation.[13]

Later research hinged on the discovery that allyl acetoacetates decarboxylate and regioselectively alpha-allylate in the presence of catalytic Pd(OAc)2 and PPh3 via the intermediacy of an allylpalladium enolate[14] - a catalytic Carroll rearrangement. Following work revealed that replacement of PPh3 in the reaction mixture with the bidentate ligand dppe could favor beta-hydride elimination of the palladium enolate, yielding enones.[15] This transformation was applied by Tsuji to the racemic synthesis of methyl jasmonate.[16] Tsuji also found that the palladium enolate could be engaged in intramolecular aldol reactions.[17]

Awards[edit]

  • 1994 - Purple ribbon medal of honor
  • 2004 - Japan Academy Prize, for "research on new organic synthesis reactions using palladium catalysts"[18]
  • 2014 - Tetrahedron Prize
