the generation of unprecedented vinyl carbenoids from sulfoxonium ylides has been developed and applied in the synthesis of a diverse array of heterocycles such as indolizines, pyrroles, 3‐pyrrolin‐2‐ones, and furans. The reactions proceed by FeBr2 catalysis under mild reaction conditions with a broad substrate scope. A reaction pathway involving iron carbenoids is proposed based on a series of control

The present disclosure provides a series of compounds which exhibit isoform selective inhibition of GRP94, a homologue of Hsp90 that is localized to the endoplasmic recticulum. Through GRP94 inhibition, these compounds are likely to manifest anti-cancer, anti-inflammatory, anti-metastasis, and immunosuppressive activities, as well as utility in the treatment of neurodegenerative diseases, and diabetes.

Synthesis and biological activities of new furo[3,4-b]carbazoles: Potential topoisomerase II inhibitors
topoisomerase I or II except for one promising compound. This compound is a potent topoisomerase II inhibitor, and its cellular activity is not moderated compared to etoposide. The synthesis of these molecules allowed the generalisation of the method using indole and 5-OBn indole and several benzaldehydes. The synthesis of these molecules produced chemical structures endowed with promising cytotoxic and topoisomerase
