| | 4-Bromo-1-butene Usage And Synthesis |
| Chemical Properties | colourless liquid | | Uses | 4-Bromo-1-butene is a brominated alkene used as a reagent in organic synthesis. | | Uses | 4-Bromo-1-butene is used in the preparation of 4-(3-butenyloxy)benzoic acid and largazole. It is also used in double alkylation of lactams followed by Grubbs ring-closing metathesis to yield gymnodimine. Further, it serves as a reagent in the preparation of dienehydrazides. | | Synthesis Reference(s) | Tetrahedron Letters, 25, p. 251, 1984 DOI: 10.1016/S0040-4039(00)99853-8 | | General Description | Stereoselective epoxidation of 4-bromo-1-butene was carried out with three alkene-utilizing bacteria: Mycobacterium LI, Mycobacterium E3 and Nocardia IP1. |
