DOI: 10.1002/ejoc.202500193

Abstract: Indole‐based heterocycles are commonly found in natural products and pharmaceuticals, so the synthesis of such heterocycles has become an important research area. In spite of the rapid development of this research area, the synthesis of… read more here.

DOI: 10.1021/acs.orglett.2c01489

Abstract: α-Ketoamides have been found to be an important functional group in a broad spectrum of inhibitors such as the Corona virus and other viruses. Here we report an unprecedented gold-catalyzed 2-fold reaction of a bromoalkyne… read more here.

DOI: 10.1039/d1cc06388j

Abstract: Cycloisomerization of N-tethered indole- and dihydropyrrole-arylpropargyl substrates into complex polycycles was investigated by using gold(I) catalysis. Enantioselectivities up to 93% ee were obtained in the asymmetric version of this process. DFT calculations rationalized the reactivity… read more here.

DOI: 10.1088/1361-6528/ac8556

Abstract: Glass embedded with metal nanoparticles is a promising material necessary for optical devices because of its absorption properties associated with the surface plasmon resonance (SPR) of metal nanoparticles. We demonstrated that continuous-wave laser illumination of… read more here.
