Systemic polyfunctionality and morphology–syntax interdependencies

, 2017
Abstract The chapter examines classes of grammatical markers that can serve more than one function, polyfunctional markers, spoiling the one-to-one form and function relation which is what morphology tends to do. There are areas of the grammar more prone to this behaviour suggesting that there may be at work principles of morphological ...

One-pot synthesis of polyfunctionalized, alpha, beta-unsaturated nitriles from nitroalkanes

, 2003
The reaction of nitroalkanes with 2-chloro-3-phenylsulfonylpropanenitrile, in the presence of three equivalents of DBU at −10°C, allows the synthesis of polyfunctionalized α,β-unsaturated nitriles.

Application of the nitroaldol (Henry) reaction for a two-step sequence in the synthesis of polyfunctionalized dihydropyran derivatives

, 2007
Nitroaldol (Henry) reaction of a variety of nitroalkanes, under neat t-BuOK catalysis, allows a one-pot synthesis of polyfunctionalized tetrahydropyranols which, with CeCl3-7H(2)O/NaI system, dehydrate to dihydropyran derivatives. Thus, the dibydropyrans
