The crude product was purified by column chromatography (performed with hexanes/CH2Cl2 1 : 1, followed by CH2Cl2). 40 min); >99% ee; ½aŠ25 D ¼ þ 65:4 (20 mg/2 mL, CH2Cl2). ), followed by (S)-isopropyl-trisoxazoline L7. 005 mol mLÀ1. ) was added to the mixture. ) was added. After the reaction was complete (monitored by TLC), the reaction mixture was concentrated under reduced pressure at room temperature, and the residue was purified by flash column chromatography on silica gel [eluted with CH2Cl2/petroleum ether (1/1, v/v) then pure CH2Cl2].

1 Alkylidene Malonates Jørgensen et al. documented the first effective catalytic and enantioselective FC alkylation of olefins. The method consists of the conjugate addition of indoles to the aryl-substituted methylidene malonates 1 in the presence of a catalytic amount (10 mol%) of L1-Cu(OTf)2 complex as promoter [8]. 1). Competent alkylidene malonates were restricted to those bearing aryl groups at the Cb position. The diethyl 2-chlorobenzylidene malonate derivative was less reactive than the other malonates and required 30  C for the reaction to go to completion (entry 5).

Several bis(oxazoline) ligands revealed L12-Cu(OTf)2 as the best catalyst. r. 16, entry 1). The reaction in toluene gave high yield and diastereoselectivity (70 : 30), and the enantiomeric excess of the anti-isomer was high (96%) while that of the syn-isomer was very poor (9%). The yields of the product decreased when the reaction was carried out in THF or iPrOH. Generally, the indoles bearing the substituents at the 5-position reacted with Z-nitroacrylates smoothly to afford the corresponding products in good yields with excellent enantioselectivities of anti-isomers (82–99% ee), but moderate diastereoselectivities and enantioselectivities of syn-isomers.
