Highly Enantioselective Hydrogenation of β‐Alkyl and β‐(ω‐Chloroalkyl) Substituted β‐Keto Esters
摘要:
Highly enantioselective hydrogenation of beta-alkyl and beta-(omega-chloroalkyl) substituted beta-keto esters was achieved with Ru catalysts based on chiral diphosphinesin EtOH at 50 degrees C under 50-bar initial hydrogen pressure, affording the corresponding beta-hydroxy esters in > 98% ee.

Treatment of N-(2-bromoaryl) enaminones 4, prepared by several different methods, with palladium (II) acetate, triarylphosphine and triethylamine in boiling acetonitrile gave pyrrolo[1,2-a]indoles 8 yields of 50% – 100%. The hydroxy-substituted products 8k could be oxidised to the mitosene-like quinone 9 with Fremy's salt.
