Abstract

Abstract A series of substituted 4H-pyrans derivatives were synthesized by a one-pot, multi-component reaction of aromatic aldehydes, malononitrile, and pyrazolone derivatives or active methylene carbonyl compounds such as dimedone, in the presence of 1,3-dimethyl imidazolium dimethyl phosphate [DMImd-DMP] as a catalyst in aqueous ethanol. Recyclability of the catalyst, high yields, simple product isolation and high atom economy are the noteworthy aspects of this protocol.

[DDMMD-DMP]：一种用于合成4H-苯并[b]吡喃衍生物的高效且可重复使用的催化剂

摘要以1,3-二甲基咪唑二甲基磷酸[dmid - dmp]为催化剂，以芳香醛、丙二腈、吡唑酮衍生物或二美酮等活性亚甲基羰基化合物为原料，在乙醇水溶液中进行一锅多组分反应，合成了一系列取代的4h -吡喃衍生物。催化剂的可回收性、产率高、产物分离简单、原子经济性高是该工艺值得注意的方面。

期刊介绍： Heterocyclic Communications (HC) is a bimonthly, peer-reviewed journal publishing preliminary communications, research articles, and reviews on significant developments in all phases of heterocyclic chemistry, including general synthesis, natural products, computational analysis, considerable biological activity and inorganic ring systems. Clear presentation of experimental and computational data is strongly emphasized. Heterocyclic chemistry is a rapidly growing field. By some estimates original research papers in heterocyclic chemistry have increased to more than 60% of the current organic chemistry literature published. This explosive growth is even greater when considering heterocyclic research published in materials science, physical, biophysical, analytical, bioorganic, pharmaceutical, medicinal and natural products journals. There is a need, therefore, for a journal dedicated explicitly to heterocyclic chemistry and the properties of heterocyclic compounds.
