Morita–Baylis–Hillman reaction of acrylamide with isatin derivatives
The Morita-Baylis-Hillman reaction of acrylamide, as an activated alkene, has seen little development due to its low reactivity. We have developed the reaction using isatin derivatives with acrylamide, DABCO as a promoter and phenol as an additive in acetonitrile. The corresponding aza version with acrylate and acrylonitrile has also been developed resulting in high product yields.
متن کامل[Fluorophothometric determination of aldehyde by utilizing condensation reaction with resorcinol].
A simple and sensitive fluorophotometric method for the determination of aldehyde was established by utilizing condensation reaction with resorcinol. In the determination of vanillin that is one of aldehydes, the calibration curve exhibited linearity over the vanillin concentration range of 3.0-7600 ng ml(-1) at an emission wavelength of 507 nm with an excitation of 410 nm and with the relative...
متن کاملHighly enantioselective aza-Henry reaction with isatin N-Boc ketimines.
A highly enantioselective aza-Henry reaction with isatin N-Boc ketimines using a Cu(II)-BOX complex as a catalyst is described. The reaction, which does not require protection of the N1 atom, provides the corresponding nitroamines bearing a quaternary stereocentre with high yields and enantiomeric excesses (up to 99.9%).
