Electric Literature of C9H9NO. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 3-Hydroxy-3-phenylpropanenitrile, is researched, Molecular C9H9NO, CAS is 17190-29-3, about Study of the enantioselectivity of the CAL-B-catalyzed transesterification of α-substituted α-propylmethanols and α-substituted benzyl alcohols. Author is Garcia-Urdiales, Eduardo; Rebolledo, Francisca; Gotor, Vicente.
A study of the enantioselectivity exhibited by the lipase B from Candida antarctica in the transesterification of different α-substituted α-propylmethanols with vinyl acetate is shown. The best results are obtained when the large-sized (L) substituent of the alc. is either a Ph group or more especially a cyclohexyl group, although the reaction rates are lower than when linear or slightly branched groups are present. It is also found that ramification at the β-position of the L substituent has a deleterious effect on both lipase activity and enantioselectivity. Moreover, some α-substituted benzyl alcs. bearing medium-sized (M) substituents larger than an Et and smaller than a Pr group are resolved by means of this methodol. with moderate-good enantioselectivities (E = 46-57) and similar reaction rates.
As far as I know, this compound(17190-29-3)Electric Literature of C9H9NO can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
