An unprecedented palladium-catalyzed carbene/alkyne metathesis reaction of alkyne-tethered enynones is described, which delivers fused-furans in moderate to good yields.
Propiolophenone derivatives of the formula ##STR1## wherein R.sup.6 is hydrogen, lower alkyl or a group of the formula ##STR2## as well as corresponding hydroxy compounds of the formula ##STR3## wherein R.sup.6' is hydrogen, lower alkyl, a group of formula (a), (b), (c), (d) or (e) or a group of the formula --C(R.sup.14)(R.sup.15)OR.sup.16' (f'): exhibit mucosa-protective and/or gastric acid secretion-inhibiting properties, such that they can be used for the control or prevention of illnesses of the gastrointestinal tract, especially against gastric ulcers and/or duodenal ulcers.
A series of thirty one melampomagnolide B-triazole conjugates was synthesized via Copper(I) oxide nanoparticles catalyzed click chemistry. These conjugates were evaluated for their anti-cancer activities against a panel of five human cancer cell lines. The most active compound 6e showed high activity against HCT116 cell line with IC50 value of 0.43 μM, which demonstrated 11.5-fold improvement compared

A novel method for the synthesis of diversely functionalized pyrazolo[5,1-a]isoindol-8(3aH)-ones is developed via phosphine-catalyzed tandem Michael addition/intramolecular Morita–Baylis–Hillman reaction of electron-deficientalkynes and N-amino substituted phthalimide. This cyclization is operationally simple under metal-free reaction conditions.
通过膦催化串联迈克尔加成反应/缺电子炔烃和氮的分子内Morita-Baylis-Hillman反应,开发了一种新颖的合成功能多样的吡唑并[5,1- a ] isoindol-8(3 aH)-ones的新方法-氨基取代的邻苯二甲酰亚胺。在无金属的反应条件下,这种环化操作简单。
