Studies with Enamines: Route to Aminoazolopyrimidines and Arylazoazolopyrimidines
The chemistry of azolopyrimidines has in the past received considerable interest [1 – 5] and is still an area of major interest [6, 7]. Recently azoloazines have been shown to be of antimicrobial, antioxidant [8] and agrochemical importance. Moreover they are a promising new class of dyes for D2T2 printing and hair dyes [9, 10]. Microwave heating has been employed as a frequent resource for the...
متن کاملa synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
15 صفحه اولRelative tendency of carbonyl compounds to form enamines.
Equilibria between carbonyl compounds and their enamines (from O-TBDPS-derived prolinol) have been examined by NMR spectroscopy in DMSO-d(6). By comparing the exchange reactions between pairs (enamine A + carbonyl B → carbonyl A + enamine B), a quite general scale of the tendency of carbonyl groups to form enamines has been established. Aldehydes quickly give enamines that are relatively more s...
متن کاملOrganocatalytic Michael addition of 1,3-dicarbonyl indane compounds to nitrostyrenes.
To map out the efficient organocatalyst requirements in the Michael addition of 1,3-dicarbonyl indane compounds to nitrostyrenes, a dozen different amino organocatalysts containing a p-toluenesulfonyl group (Ts) have been evaluated; excellent enantio-selectivities (up to er 92:8) were obtained with a primary amine-based Ts-DPEN catalyst and a plausible catalytic reaction mechanism was proposed ...
