    Abstract : The demand for energy is rapidly increasing, triggering more carbon emission and global warming. Alternative green energy sources are essential to secure the future generation from the effect of pollution and global warming. READ MORE

  7. 15. Synthesis and [3,3]-Sigmatropic Rearrangement of Vinylaziridines

    Author : Ulf Lindström; Torbjörn Frejd; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : A general synthetic route from vinylepoxides to vinylaziridines via 1,2-amino alcohols was developed. The 1,2-amino alcohols were obtained from a stereospecific and regioselective aminolysis of vinylepoxides. The synthetic scope of the aminolysis could be expanded by the use of a microwave-assisted protocol. READ MORE
