M. Shi and Y.-L. Shi reported the synthesis and application of new bifunctional axially chiral (thio) urea-phosphine organocatalysts in the asymmetric aza-Morita-Baylis-Hillman (MBH) reaction [176, 177] of N-sulfonated imines with methyl vinyl ketone (MVK), phenyl vinyl ketone (PVK), ethyl vinyl ketone (EVK) or acrolein [316]. The design of the catalyst structure is based on axially chiral BINOL-derived phosphines [317, 318] that have already been successfully utilized as bifunctional catalysts in asymmetric aza-MBH reactions. The formal replacement of the hydrogen-bonding phenol group with a (thio)urea functionality led to catalysts 166-168 (Figure 6.51). 

Janus [11] has recently shown that urea can also be smoothly methylated with methyl toluene-p-sulfonate at 80°-90°C to give good yields of crystalline 2-methylpseudourea toluene-p-sulfonate. 

Another way of producing a low proton activity at the amalgam surface is to add a suitable polar, aprotic compound to the medium. Suitable compounds include urea and its derivatives, amides, lactams, sulfoxides, and sulfones, such as 1,3-dimethylurea, ethyle-neurea, biuret, formamide, A-methyl formamide, acetamide, 5-butyrolactam, dimethyl sulfoxide, di- -butyl sulfoxide, and dimethyl sulfone [41,42]. Dimethylformamide (DMF) or acetonitrile, besides some of the compounds just mentioned, may be used as solvents [43,44]. One function of the added compound is to establish an aprotic reaction layer at the amalgam surface by selective adsorption of the compound on the amalgam another is to solvate the ion pair (consisting of the radical ion and the cation) in a suitable way. 

Addition of sulfides and sulfones to acid derivatives has been investigated by Agawa. Phenyl and methyl (trimethylsilyl)methyl sulfides and sulfones added to amides (323) to produce the aminovinyl sulfides (324 equation 74) and sulfone (326 equation 7S). The reactions proceeded in good yield with some examples of stereocontrolled synthesis of the ( )-isomer. Other acid derivatives such as esters, carbonates and ureas were investigated, but gave inconsistent results. 

The best known and most widely used diazoalkane is diazomethane (95 equation 39). Preparative methods for diazomethane involve, in general, the nitrosation of a methylamine derivative (93), followed by cleavage under alkaline conditions. Methylamine derivatives used have included the urethanes, ureas,carboxamides, sulfonamides, guanidines and even the methylamine adducts of unsaturated ketones and sulfones. N-nitroso-N-methyl p-toluenesulfonamide (Diazald, Aldrich) is currently the most commonly used diazomethane precursor. Diazomethane is both toxic and explosive. Although in the past it has been purified by codistillation with ether, it is now usually generated, stored and used as an ether solution without distillation.
