Mass spectrometry of Avermectins: structural determination of two new derivatives of Ivermectin B 1a
Publikováno v:
Rapid Communications in Mass Spectrometry. 14:1260-1265
Fragmentation pathways of Avermectins were studied by electron impact (EI), chemical ionisation (CI), electrospray ionisation (ESI) and by collision experiments. Structure characterisation was obtained using ESI combined with multi-stage (MSn) tandem

Irradiation of 1,4-dimethoxynaphthalene (DMNH) in the presence of 4-substituted benzyl chlorides (X–C₆H₄CH₂Cl, X = H, Cl, CN OR NO₂) in either acetonitrile or benezene solution results in benzylation of DMNH, predominantly at position 2 and
