| | Ethyl 2 3-butadienoate 95 Usage And Synthesis |
| Uses | Ethyl 2,3-butadienoate may be used in the synthesis of dihydropyrans by reacting with acyclic enones. It may also be used to synthesize spiranic heterocycles by reacting with heterocyclic bis-arylidene ketones via phosphine-catalyzed [3+2] annulations. | | Uses | Ethyl Buta-2,3-dienoate is a useful reactant for the synthesis of 9H-pyrrolo[1,2-a]indole derivatives via a phosphine-promoted Michael addn./intramol. Wittig reaction. | | General Description | Ethyl 2,3-butadienoate is an α-allenic ester. The reaction of ethyl 2,3-butadienoate with N-tosylated imines in the presence of DABCO (1,4-diazabicyclo[2.2.2]octane) or DMAP (4-dimethylaminopyridine) forms azetidine derivatives or novel dihydropyridine derivatives respectively. The performance of bifunctional N-acyl aminophosphines to catalyze the asymmetric [3+2] cycloaddition of phenylidenemalononitrile with ethyl 2,3-butadienoate has been evaluated. |
