Stereoselective Synthesis of Biologically Relevant Tetrahydropyridines and Dihydro-2 H-pyrans via Ring-Expansion of Monocyclopropanated Heterocycles
{{output}}
A stereoselective, scalable, and metal-free ring-expansion of monocyclopropanated pyrroles and furans has been developed, leading to value-added highly functionalized tetrahydropyridine and dihydro-2H-pyran derivatives. Featuring a cyclopropylcarbinyl cation r... ...
