An effective three-component fixation of atmospheric CO2 with readily available 1,2-dichloroethane and aromatic amine toward oxazolidinones catalyzed by in situ NHC was developed. The reaction occurred in good to excellent yields with good gene

, p. 1659 - 1663 (2007/10/02)
The cycloadditions of carbon dioxide, isocyanates and carbodiimides to oxetanes proceeded in the presence of catalytic amounts of tetraphenylstibonium iodide (1) under mild conditions, affording the corresponding six-membered heterocycles; 1,3-dioxan-2-ones, 1,3-oxazin-2-ones and 1,3-oxazin-2-imines in good yields, respectively.Moreover, the cycloaddition of 2-phenyloxetane proceeded via predominant ring-cleavage at substituted site.

, p. 361 - 363 (2007/10/02)
A series of 2-oxazinones 1-8 were synthesized from the cycloaddition reactions of oxetanes with isocyanates by utilizing the complex of diphenyltin diiodide with hexamethylphosphoric triamide (HMPA) as a catalyst.Moreover, the reactions with carbodiimides
NOVEL USE OF ORGANOTIN HALIDE-BASE COMPLEX IN ORGANIC SYNTHESIS. CYCLOADDITION REACTION OF OXETANE WITH ISOCYANATES.
Baba, Akio,Shibata, Ikuya,Fujiwara, Masahiro,Matsuda, Haruo
, p. 5167 - 5170 (2007/10/02)
Cycloadditions of oxetanes with isocyanates were markedly accelerated by the complex of Bu2SnI2 and Ph3P=O which could be readily handled and hardly caused a trimerization of isocyanates, yielding oxazin-2-ones under neutral and mild reaction conditions.
