PALLADIUM(0) CATALYZED REACTIONS OF 1,4-EPIPEROXIDES
Suzuki, Masaaki,Oda, Yoshihisa,Hamanaka, Nobuyuki,Noyori, Ryoji
, p. 517 - 535 (2007/10/02)
The Pd(PPh3)4 catalyzed reaction of 2,3-saturated and 2,3-unsaturated 1,4-epiperoxides proceeds by courses markedly different from those of the previously reported transition metal catalyses.The Pd(0)-promoted reaction of 2,3-saturated epiperoxides gives the corresponding 4-hydroxy ketones and 1,4-diols as the major products.From 2,3-dedihydroepiperoxides are formed the corresponding 4-hydroxy enones, syn-1,2;3,4-diepoxides, and 1,4-diols.The results are interpreted in terms of competing Pd(0)/Pd(II) exchange mechanisms.Exposure of prostaglandin (PG) H2 methyl esterto Pd(PPh3)4 produces a mixture of methyl esters of PGD2, PGE2, PGF2α, and (5Z,8E,10E,12S)-12-hydroxy-5,8,10-heptadecatrienoic acid.
PROSTAGLANDINS: TOTAL SYNTHESIS OF PGD2 "via" 1,3 CYCLOPENTANEDIONE
Cainelli, Gianfranco,Giacomini, Daria,Panunzio, Mauro,Martelli, Giorgio,Spunta, Giuseppe
, p. 1385 - 1392 (2007/10/02)
A practical total synthesis of PGD2 starting from an acyclic precursor is reported.A novel efficient inversion of stereochemistry at C9 tosylate group "via" a SN2 displacement by tetrabutylammonium nitrate is described.
