In the title compound, C(12)H(13)NO(2), the dihedral angle between the benzene ring and the imide segment is 85.7 (1)°. In the crystal, the mol-ecules are packed into zigzag chains parallel to the a axis.

A rhodium(III)-based catalytic system has been used to develop a C−H bond activation of benzaldehyde derivatives and subsequent functionalization with dioxazolones in order afford imides. The importance the nature directing group perform selectively aldehydic highlighted. scope investigation showed that this transformation could be applied various many as well an acrolein derivative. Derivatiza...

PolyPOSS-imides are hybrid hyper-cross-linked networks based on inorganic octa(aminopropyl)silsesquioxane (POSS) cages covalently bonded via organic imide bridges. They were initially developed for separations under harsh conditions, but they cannot be used above 300 °C due to the decomposition of their –(CH2)3– propyl linkers. Replacing aliphatic-arm POSS with its phenyl-arm derivative, octa(a...

We report the first study of substrate-controlled diastereoselection in a double [3 + 2] dipolar cycloaddition of benzyl azide with α,β-unsaturated imides. Using a strong Brønsted acid (triflic acid) to activate the electron deficient imide π-bond, high diastereoselection was observed provided that a 1,1,3,3-tetraisopropoxydisiloxanylidene group (TIPDS) is used to restrict the conformation of t...

[reaction: see text] A general strategy for highly enantioselective 1,3-dipolar cycloaddition of diazoesters to beta-substituted, alpha-substituted, and alpha,beta-disubstituted alpha,beta-unsaturated pyrazolidinone imides is described. Cycloadditions utilizing less reactive alpha,beta-disubstituted dipolarophiles require elevated reaction temperatures, but still provide the corresponding pyraz...

Z. Naturforsch. 61b, 431 – 436 (2006); received January 17, 2006 The 3,4-substituted 2-oxo-piperazines 5 – 9 are obtained by [3+2] cycloaddition from nitrone 1 and a variety of alkenes. Subsequent functionalization of the bicyclic adducts involves reductive N-O bond cleavage. A route towards libraries of immobilized 1,3-aminoalcohols with a 3,4-substituted 2-oxo-piperazine scaffold is briefly d...

In this review, the recent developments in catalytic asymmetric inverse-electron-demand hetero-Diels-Alder reaction, which is recognized as one of the most powerful routes to construct highly functionalized and enantioenriched six-membered heterocycles, are described. The article is organized on the basis of different kinds of electron-deficient heterodienes, including α,β-unsaturated ketones/a...
