Dw. Ma et al., Facile synthesis of (+)-alpha-allokainic acid via Pd-catalyzed hydrogenolysis of allyl acetate derived from trans-4-hydroxy-L-proline, TETRAHEDR L, 42(39), 2001, pp. 6929-6931
Pd(PPh3)(4)/PPh3-catalyzed hydrogenolysis of 3a derived from trans-4-hydrox
y-L-proline using ammonium formate as a hydride reagent, provides olefin 4
as a major product, which is hydrolyzed to give (+)-alpha -allokainic acid.
