Description General description Thermal inverse-type hetero-Diels-Alder reaction of O-silyl-protected lactal and bis(2,2,2-trichloroethyl) azodicarboxylate has been reported. Application Bis(2,2,2-trichloroethyl) azodicarboxylate has been used: • in the asymmetric synthesis of substituted cycloalkyl[b]indoles • as amination reagent during the aza-ene reaction of different alkenes to yield the corresponding allyl amines • in para-directed amination of C2-alkyl substituted anisole • in the synthesis of acid- and base-sensitive azo compounds and in Diels-Alder cycloadditions Packaging 5 g in glass bottle
