Efficient and stereoselective installation of isoquinoline: formal total synthesis of cortistatin A

The highly stereoselective attachment of isoquinoline onto the steroidal framework of cortistatin A has been achieved. Our strategy features a Ce-mediated nucleophilic addition of an isoquinoline unit to the sterically congested ketone followed by formation of the phenyl thiocarbamate, and Subsequent stereoselective radical reduction. The new method results in a formal total synthesis of cortistatin A. (C) 2009 Elsevier Ltd. All rights reserved.

Investigation of fragmentation behaviours of isoquinoline alkaloids by mass spectrometry combined with computational chemistry

Isoquinoline alkaloids, which are one of the most important types of alkaloids, are extensively distributed in herbal medicines. However, systematic and comprehensive investigations of the fragmentation behaviours of isoquinoline alkaloids have rarely been reported. Therefore, the goal of the present study is to simultaneously investigate the collision-induced dissociation patterns and the corresponding mechanism of isoquinoline alkaloids by mass spectrometry (MS) combined with computations. Nineteen types of isoquinoline alkaloids (66 compounds) were used as references to identify the characteristic fragmentation behaviours by quadrupole time-of-flight mass spectrometry (Q-TOF/MS) in positive electrospray ionization (ESI) mode. These types of isoquinoline alkaloids were divided into three categories primarily by the characteristic [M-NHR1R2](+) (R-1 and R-2 represent the substituent groups of the N-atom) fragment ions. High- and low-abundance [M-NHR1R2](+) ions were observed respectively for type I (1-13) and type II (14-29) alkaloids, respectively; however, the characteristic fragments were not detected for type III alkaloids (30-66) because of the existence of a p-pi conjugated system. Each type of alkaloid was further classified by its characteristic fragmentation patterns and fragment ions. In addition, isoquinoline alkaloid with vicinal methoxy and hydroxy, vicinal methoxy, methylenedioxy, methoxy, and quaternary N-methyl groups could form the characteristic fragments by the loss of CH3OH, CH4, CH2O or CO, CH3 and CO, and CH3 moieties, respectively. The mechanisms of some interesting fragmentation behaviours, such as the formation of [M-NH3](+) and [M-CH3](+) fragment ions, were further demonstrated by computational chemistry. These characteristic fragmentation behaviours and fragment ions of isoquinoline alkaloids provide a solid foundation for the rapid and high-efficiency structural elucidation of similar metabolites in plant-derived medicines.

Isoquinoline alkaloids: a N-15 NMR and x-ray study. Part 2

Continuing our systematic N-15 NMR study of isoquinoline alkaloids, we report a contribution extending our previous paper. The N-15 NMR chemical shifts and N-15,H-1 long-range coupling pathways of tertiary and quaternary isoquinoline alkaloids of several constitutional types are presented. The selected compounds belong to the protoberberine, proaporphine, pavinane, rhoeadine and phtalideisoquinoline classes of alkaloids and were investigated by gradient-selected inverse-detected multiple bond correlation experiments (GHMBC and GSQMBC). In addition, x-ray data and the principal geometric parameters of stylopine, mecambridine, norchelerythrine, isothebaine and mecambrine are reported and discussed.

Bromination of isoquinoline, quinoline, quinazoline and quinoxaline in strong acid

Bromination of benzazines and benzodiazines most often gives a mixture of products. In this paper, we show that isoquinoline (1) may be regioselectively monobrominated in concentrated H2SO4 using NBS or in CF3SO3H using N,N’-dibromoisocyanuric acid (DBI) to give 5-bromoisoquinoline (2). The bromination was found to be highly sensitive to the choice of brominating agent, acid, temperature and concentration. Quinoline. quinazoline and quinoxaline may be brominated likewise, although with the strong regioselectivity reserved to isoquinoline.
