General description

Thermal inverse-type hetero-Diels-Alder reaction of O-silyl-protected lactal and bis(2,2,2-trichloroethyl) azodicarboxylate has been reported[1].

application

Bis(2,2,2-trichloroethyl) azodicarboxylate has been used:
  • in the asymmetric synthesis of substituted cycloalkyl[b]indoles[2]
  • as amination reagent during the aza-ene reaction of different alkenes to yield the corresponding allyl amines[3]
  • in para-directed amination of C2-alkyl substituted anisole[4]
  • in the synthesis of acid- and base-sensitive azo compounds and in Diels-Alder cycloadditions[5]

A general asymmetric synthesis of substituted cycloalkyl[b]indoles has been accomplished. The key features of this approach are (1) the utilization of a Japp-Klingemann condensation/Fischer cyclization to prepare cycloalkyl[b]indolones, (2) the asymmetric borane reduction of these heterocyclic ketones with (S)-OAB to

In a thermal inverse-type hetero-Diels-Alder reaction of O-silyl-protected lactal 1 and bis(2,2,2-trichloroethyl) azodicarboxylate (2), the dihydrooxadiazine derivative 3 was obtained in a very high yield; transesterification with benzyl alcohol furnished the corresponding derivative 4. Treatment of 3 with methanol in

Lewis acids such as Cu(OTf)(2), Zn(OTf)(2), Yb(OTf)(3) and Nd(OTf)(3) catalyze the aza-ene reaction of alkenes with azodicarboxylates, giving the allylic amination adducts. The use of bis(2,2,2-trichloroethyl)azodicarboxylate as the amination reagent and Cu(OTf)(2) and Yb(OTf)(3) as the catalysts gave the aza-ene
