Synthesis of Alkoxymethyl Groups Containing Isoxazoles and Chromones

Abstract

An oxocarbenium ion mediated cyclization of (Z)-1,3-diarylprop-2-yn-1-one O-methyloximes and 3-arylprop-2-yn-1-(2-methoxyphenyl)-1-ones resulted in regioselective formation of functionalized isoxazoles and chromones, respectively. Alkoxy(aryl)methyl group containing compounds were obtained in good and high yields.

Convenient Preparation, Thermal Properties and X-ray Structure Determination of 2,3-Dihydro-5,6,7,8-tetranitro-1,4-benzodioxine (TNBD): A Promising High-Energy-Density Material

“…Later, in the same laboratory, the nitro and amino derivatives of 1,4-benzodioxane were used as a core structural fragment for the synthesis of novel annulated O,N-heterocyclic derivatives [43][44][45][46][47].…”
