Provided herein are methods for preparing alkylfurans, such as 2,5-dialkylfurans and 2-alkylfurans. Furfural or 5-alkylfurfural can be reacted with aniline or diaminobenzene, or derivatives thereof, to form the corresponding imine, which can be reduced to form alkylfurans and to regenerate the aniline or diaminobenzene, or derivatives thereof. The alkylfuran may be, for example, 2,5-dimethylfuran or 2-methylfuran.

Reported here is the development of an environmentally friendly catalytic (KBr/oxone) and solvent-free protocol for the Achmatowiczrearrangement (AchR). Different from all previous methods is that the use of chromatographic alumina (Al2O3) allows AchR to proceed smoothly in the absence of any organic solvent and therefore considerably facilitates the subsequent workup and purification with minimal
这里报道的是针对Achmatowicz重排(AchR)的环保型催化(KBr / oxone)和无溶剂方案的开发。与所有以前的方法不同的是,使用色谱氧化铝(Al 2 O 3)可使AchR在不存在任何有机溶剂的情况下顺利进行,因此可极大地促进后续的后处理和纯化,并且对环境的影响最小。重要的是,该协议允许按比例放大(从毫克到克),回收Al 2 O 3以及与其他反应按一锅顺序方式进行整合。

The present invention relates to an isolated bacterium and composition comprising same having anti-pathogenic activity. The invention further relates to compounds derived from said bacterium or analogs thereof, and methods of using same for treating or reducing the symptoms of a pathogen including but not limited to a phytopathogen.
A previously unreported activation mode is developed through the generation of dearomatizative tetraenamine species between 5-allylic furfurals and a bifunctional amine-thiourea catalyst. The very remote zeta,eta-alkenes perform as effective HOMO-raised dienophiles in inverse-electron demand oxa-Diels-Alder cycloadditions with isatin-derived oxadiene substrates, delivering multifunctional spirocyclic oxindoles incorporating a dihydropyran skeleton in moderate to high yields with good to excellent enantio- and diastereoselectivity.
