Cativiela,Mayoral,Avenoza,Gonzalez,Roy
, p. 1114 - 1116 (1990)
The application of 2-phenyl-4-benzylidene-5(4H)-oxazolone (1) as a dienophile in the synthesis of 2-amino-2-bicycloalkanecarboxylic acids is described. The influence of different Lewis acids and the reaction conditions are discussed.
(Z)- and (E)-2-Phenyl-4-benzylidene-5(4H))oxazolones as Dienophiles. Improved Selectivity by the Use of Heterogeneous Catalysts

Silica gel treated with AlEt2Cl or TiCl4 efficiently promotes the reaction of cyclopentadiene with (Z)-2-phenyl-4-benzylidene-5(4H)-oxazolone (1a) with very little Z/E isomerization.Silica gel treated with TiCl4 and ZnCl2 supported on silica gel leads to
Synthesis of the four d,1-pairs of 2-amino-3-phenylnorbornane-2-carboxylic acids II. The use of 5(4H)-oxazolones as dienophiles

, p. 677 - 684 (2007/10/02)
The Diels-Alder reaction between both geometric isomers (Z)- or (E)-2-phenyl-4-benzylidene-5(4H)-oxazolone and cyclopentadiene is studied. The cycloadducts are converted into the aminoacids through simple reactions allowing the synthesis of the four d,1-p
