Two new terpenoids, saponaceolide T (7), and lanostane triterpenoid saponaceol D (11), were isolated from an EtOAc extract of Tricoloma saponaceum fruiting bodies and their structures have been established by spectroscopic analysis. In addition, know

The electrospray ionization mass spectrometry (ESI-MS) behavior of seven Cu(II) complexes with tetradentate ligands has been studied. An unexpected reduction process, in positive ion mode, of the Cu oxidation state was observed, and shown to be due t
Mass spectrometry of Avermectins: structural determination of two new derivatives of Ivermectin B 1a

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

Olive oil phenolic and secoiridoid compound derivatives were detected by mass spectrometry. Chemical ionization (CI) allowed us to obtain parent ions, that were not detectable in the electron impact mode. CI experiments were performed using either CH

H-1,2-Dithiolo[3,4-b]pyridine-3-thione (10) reacts with primary alkylamines to give 1,2-dihydro-2-thioxo-3-pyridinecarbothioamides 11a-g and two minor products (12a-g and 13a-g). Isothiazolo[5,4-b]pyridine-3(2H)thiones 12a-g and 3-imino-3H-1,2-dithio

Three new lanostane triterpenes, hebelomic acids B[4], E[5], and F[6], were isolated from the inedible mushroom Hebeloma senescens. The latter two compounds are acyl derivatives of the new triterpene senescensol (12-deoxycrustulinol) [12]. The struct
