Example text

247 Kinetic studies indicate that the orders of aldehyde, Lewis base (LB), and TMSCN are 1, 1, and 0, suggesting an Me3 Si–LB+ CN− ion pair as an intermediate. However, chiral phosphines and amines gave very low ees. 253 Aldehyde (RCHO) and nitrile (NC–CO2 Et) react at −45 ◦ C in DCM to give the corresponding cyanohydrin ethyl carbonate, R–*CH(CN)– O–CO2 Et. The catalyst used has four components: a chiral BINAP, (1R,2S)-(−)-N methylephedrine, cinchonine, and titanium isopropanoxide. Evidence for all four being essential is presented.

IL–B− · · · R3 P+ –CH2 –CH=C(Me)–O− · · · HO–IL. 162 For the DABCO-promoted reaction of an N -p-nitrobenzenesulfonylimine with methyl acrylate, a DABCO–acrylate–imine adduct was isolated as a key intermediate. 163 The product α-(α-hydroxyalkyl)enones – Morita–Baylis–Hillman (MBH) adducts – can be formed with significant stereocontrol when an optically active thione is used. 5 times higher yield of the product (55), using reaction times of 1–3 days. It is unclear whether this is due to the relative accessibility of the β-positions of the isomers to the nucleophilic catalyst, or differential stability in the enolate intermediates.

The ee 34 Organic Reaction Mechanisms 2006 mechanism is discussed with an emphasis on the role of sulfur via comparison with the 2,5-dioxo compounds. 269 In contrast, acylacetoamides (including Weinreb amides) produce Z-adducts. Downstream reductions of carbonyl groups in the products allow access to a variety of useful materials. 270 The pKa of acetic anhydride (estimated 20) is too high, acetate is too weak a base, and the enolate would probably decompose (to ketene and acetate) at the typical reaction temperature of 180 ◦ C.
