Chemoselective reduction of the corresponding 9-nitro precursor by catalytic transfer hydrogenation afforded the title compound, a new 9-amino derivative of the antitumor alkaloid Luotonin A, in good yield. The structure of the compound was established by means of 1D and 2D 1H-NMR and 13C-NMR spectroscopy as well as by EI-MS and high-resolution ESI-MS.

The difference between evaluatively loaded and evaluatively neutralized five-factor inventory items was used to create new variables, one for each factor in the five-factor model. Study 1 showed that these variables can be represented in terms of a general evaluative factor which is related to social desirability measures and indicated that the factor may equally well be represented as separate from the Big Five as superordinate to them. Study 2 revealed an evaluative factor in self-ratings and peer ratings of the Big Five, but the evaluative factor in self-reports did not correlate with such a factor in ratings by peers. In Study 3 the evaluative factor contributed above the Big Five in predicting work performance, indicating a substance component. The results are discussed in relation to measurement issues and self-serving biases.
