Synthesis of Vinylnaphthofurans and NMR Analysis of their Photoswitching

An easy synthesis of photochromic vinylnaphthofurans by the acid-catalyzed one-pot reaction of naphthols with but-2-yne-1,4-diols is described. These uncolored polyaromatic compounds are activated by UV light, at room temperature, and converted through a stilbene-type electrocyclization into a thermally stable orange species, which can be switched back using visible light. The behavior of these photoswitches was elucidated using NMR, which allowed to identify the photoisomers and some side-products, formed after prolonged UV irradiation.

Regioselective rapid synthesis of fully substituted 1,2,3-triazoles mediated by propargyl cations

Regioselective rapid triazole syntheses at low temperature are described. Organic azides and propargyl cations generated by acids gave fully substituted 1H-1,2,3-triazoles. Most reactions could be performed in 5 min at not only rt but also -90 C. Both terminal and internal alkynes were acceptable, and the sterically bulky substituents could afford the products smoothly. Various types of three-component coupling reactions were demonstrated, and the presence of allenylaminodiazonium intermediates was indicated.
