Mass spectrometric studies of cyclopentanol derivatives in the reductive coupling of alpha,beta-unsaturated ketones assisted by samarium diiodide.
The mass spectrometric fragmentations of a series of cyclopentanol derivatives in positive fast-atom bombardment (FAB(+)) mode were investigated. The corresponding pathways proposed were confirmed by MS/MS data obtained using linked scans at constant B/E, high-resolution accurate mass data, and comparisons with corresponding information for a specifically deuterated molecule.
