Application

  • 4-Bromo-1-butene was used in the synthesis of 4-(3-butenyloxy)benzoic acid.
  • It was also used in the total synthesis of largazole.
  • It was used in double alkylation of lactams, followed by Grubbs ring-closing metathesis, to yield gymnodimine (biotoxin).
  • It was used in preparation of dienehydrazides.

General description

Stereoselective epoxidation of 4-bromo-1-butene was carried out with three alkene-utilizing bacteria: Mycobacterium LI, Mycobacterium E3 and Nocardia IP1.
