isoindoloisoquinolinones, pyrroloisoquinolinones, and benzo[a]quinolizinones were successfully assembled from the corresponding imides by using a TfOH-mediated (TfOH = trifluoromethanesulfonic acid) imidecarbonylactivation and cyclization strategy. By employing this simple method, the isoquinoline alkaloids crispine A, trolline/oleracein E, and erythrinarbine were successfully synthesized in racemic form. The reaction
Provided herein are methods of detecting anions in solution. In particular, the methods can be used to detect trace anions in solution. For example, the anions can be present in an amount of between about 500 femtomoles to about 10 millimoles.
