    Description / Table of Contents: Substituierte γ-Lactone, XXVII.  -  Bromierung von α-Benzyliden-γ-butyrolactonDie Bromierung von α-Benzyliden-γ-butyrolacton (1) mit N-Bromsuccinimid verläuft unter Allylumlagerung zu 3-(α-Brombenzyl)-2(5H)-furanon (3a). Eine Anzahl von Reaktionen mit dieser Verbindung wird beschrieben. Die Bromierung von 1 mit elementarem Brom führt zur Anlagerungsverbindung α-Brom-α-(α-brombenzyl)-γ-butyrolacton.
    Notes: The N-bromosuccinimide bromination of α-benzylidene-γ-butyrolactone (1) proceeds with allylic rearrangement to yield 3-(α-bromobenzyl)-2(5H)-furanone (3a). A number of reactions of this compound are described. Bromination of 1 with elemental bromine leads to α-bromo-α-(α-bromobenzyl)-γ-butyrolactone.

    Carbon-13 nuclear magnetic resonance spectra of ceveratrum alkaloids (1980)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 14 (1980), S. 141-144 
    Details
    ISSN: 0030-4921
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The 13C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12,14-orthoacetate-3, 16-diacetate.
