functionalization of molecules. The value of such cleavage events is maximized when paired with subsequent bond formation. Herein we report a protocol for the cleavage of an alkene C(sp3)–C(sp2) bond, followed by the formation of a new C(sp3)–S bond. This reaction is performed in nonanhydrous solvent and open to the air, employs common starting materials, and can be used to rapidly diversify natural products

Ring-forming reaction via regioselective intramolecular insertion by (phenylthio) carbene into α c-h bond of alkoxides
ω-(Phenylthio)-ω-chloroalkyl acetates were allowed to react with MeLi (3.2 equiv) to give 2-(phenylthio) cycloalkanols which were produced by the regioselective intramolecular insertion by (phenylthio) carbenes.
The present disclosure relates to methods of carbon-carbon bond fragmentation.
