Application
trans -1-Bromo-1-propene is suitable for the synthesis of (E)-hex-4-en-2-yn-1-ol. trans -1-Bromo-1-propene ((E)-1-bromo-1-propene) may be used in the synthesis of the following:
- (E)-1,3-dimethyl-3-(prop-1-enyl)indolin-2-one
- 3-alkenyl-Δ3-cephems
- (E)-1-(benzylthio)-1-propene
trans-1-Bromo-1-propene may be used as starting reagent in the synthesis of (+)-trans-isoalliin and (-)-trans-isoalliin.
General description
trans-1-Bromo-1-propene is an alkenyl halide. Product contains copper as stabilizer. Its synthesis from 1,2-dibromopropane has been reported by various researchers. Its IR spectra has been investigated.

The enantioselective alpha-arylation and alpha-vinylation of oxindoles catalyzed by Pd and a biarylmonophosphine ligand with both axial and phosphorus-based chirogenicity is reported. The resultant quaternary carbon stereocenters are formed in high enantiomeric excess, and the conditions tolerate a range of

Naturally occurring (+)-trans-isoalliin, (R(C)R(S))-(+)-trans-S-1-propenyl-L-cysteine sulfoxide, is a major cysteine sulfoxide in onion. The importance of producing it synthetically to support further research is very well recognized. The (+)-trans-isoalliin is prepared by chemical synthesis and reversed-phase (RP)-HPLC. First, S-2-propenyl-L-cysteine (deoxyalliin) is

Synthesis of 3-alkenyl-delta 3-cephems was performed successfully by cross-coupling 3-(trifluoromethylsulfonyloxy or chloro)-delta 3-cephem with alkenyl halides, e.g., vinyl bromide, trans-1-bromo-1-propene, and trans-beta-bromostyrene in an Al/cat.PbBr2/cat.NiBr2(bpy)/NMP (or DMF) system. Reduction of 3-(trifluoromethylsulfonyloxy)-delta 3-cephem into norcephalosporin was also achieved by a similar
