Wittkopp and Schreiner introduced the simple electron-deficient N,N -bis [3,5-(trif-luoromethyl)phenyl]thiourea 9 (Figure 6.3) as an efficient double hydrogen-bonding organocatalyst in a series of Diels-Alder reactions and 1,3-dipolar cycloadditions of... 

Figure 6.3 Stereoselective, chiral thiourea derivatives of achiral benchmark thiourea organocatalyst N,N -bis [3,5-(trifluoromethyl)phenyl]thiourea 9 stereoselective hydrogen-bonding thiourea organocatalysts incorporating the privileged 3,5-bis(trifluoromethylphenyl)thiourea moiety. The (thio)urea catalyst structure is the leitmotif for the chapter organization.

In 2003, Takemoto and co-workers introduced the first tertiary amrne-function-ahzed thiourea catalyst [129]. This new type of stereoselective thiourea catalyst incorporating both (R,R)-l,2-diaminocyclohexane as the chiral scaffold and the privileged 3,5-bis(trifluoromethyl)phenyl thiourea motif for strong hydrogen-bonding substrate binding, marked the introduction of the concept of bifunctional-... 

In the first part of the twentieth century, reports appeared on differences among Whites, Blacks, and Chinese in response to drugs and chemicals. During the 1920s and 1930s, individual differences in sensory perception of chemicals were studied. Human family studies showed that the failure to perceive bitterness after tasting phenyl-thiourea was transmitted from parents to...

The synthesis l-benzyl-3-phenyl-thiourea (36) requires the application of a recently described and commercialized isatoic resin (19).1 Benzyla-mine readily reacts with isothiocyanato-benzene to afford l-benzyl-3-phenyl-thiourea (36). However, excess benzylamine needs to be removed by adding resin (19), thus providing pure product (36) upon simple filtration of the amide resin formed as depicted in Fig. 15. 

Phenyl thiourea tellurium nitrate and perchlorate were isolated when nitric or perchloric acid were added to aqeuous solutions containing phenyl tellurium chloride and thiourea.
