Herein, we describe the synthesis and pharmacological profiles of novel quinuclidinyl heteroarylcarbamate derivatives. Among them, the quinuclidin-4-yl thiazolylcarbamate derivative ASP9133 was identified as a promising long-acting muscarinic antagonist (LAMA) showing more selective inhibition of bronchoconstriction against salivation and more rapid onset of action in a rat model than tiotropium bromide

6-8-6 carbon ring systems are present in numerous biologically active natural molecules. However, simple and efficient synthetic approaches to these scaffolds remain challenging. Herein, we report a versatile strategy for constructing these ring systems via Fe(NO3)3-triggered radical arylation of arenes starting from cyclopropanols. This synthetic utility has been demonstrated in the synthesis of the natural
