Advances in the field of the synthesis of amino derivatives of terpenoids
Information on the synthesis of amino derivatives of monoterpenes by the reduction of oximes by the Leuckart reaction, and by the reductive amination of ketones by amines and nitriles is generalized. The stereochemistry of the amines formed as the result of the above-mentioned reactions is discussed.
Menthylamine synthesis via gold-catalyzed hydrogenation of menthone oxime
Abstract In the current work gold nanoparticles supported on oxides (MgO, Al2O3, ZrO2, TiO2) were used for menthylamine synthesis via menthone oxime hydrogenation. An increase of the gold nanoparticles size and application of metal oxides with a strong basic character such as magnesia favored deoximation to menthone. Au/Al2O3 catalyst with the gold nanoparticles size of 2.0 nm afforded high catalytic activity and selectivity to menthylamine. The reaction kinetics including stereoselectivity to the reaction products and recyclability of the catalyst was studied using Au/Al2O3 in the temperature range 90−110 °C under hydrogen pressure of 5.5–7.5 bar. The catalytic behavior was influenced by the solvent nature, with higher selectivity to desired amine achieved using methanol. The reaction rate was pressure independent, while has first order with respect to menthone oxime concentration. Stereoselectivity to menthylamines and menthones was independent on the reaction temperature and the hydrogen pressure.
Beyond East–West: Marginality and National Dignity in Finnish Identity Construction
Since the end of the Cold War it has become common for Finnish academics and politicians alike to frame debates about Finnish national identity in terms of locating Finland somewhere along a continuum between East and West. Indeed, for politicians, properly locating oneself (and therefore Finland) along this continuum has often been seen as central to the winning and losing of elections. For example, the 1994 referendum on EU membership was largely interpreted precisely as an opportunity to relocate Finland further to the West. Indeed, the tendency to depict Finnish history in terms of a series of “Westernizing” moves has been notable, but has also betrayed some of the politicized elements of this view. However, this framing of Finnish national identity discourse is not only sometimes politicized but arguably is also too simplified and results in blindness towards other identity narratives that have also been important through Finnish history, and that are also evident (but rarely recognized) today as well. In this article we aim to highlight one of these that we argue has played a key role in locating Finland in the world and in formulating notions of what Finland is about, what historical role and mission it has been understood as destined to play, and what futures for the nation have been conceptualized as possible and as providing a source of subjectivity and national dignity.
