Exposure of enones and enals to either Bu3SnH or PhSiH3 in the presence of ≤ 5 mol % [(Ph3P)CuH]6 leads to products of 1,4-hydride delivery in good yields.
The three-component coupling process allows a single-pot entry to protected 7-hydroxy-PGE1 derivatives, leading to a variety of new PGs functionalized or unsaturated at C-7. The enone and dienone derivatives exhibit potent inhibitory activity on L1210 tumor cell growth in vitro.
