Enantioselective insertion of a carbenoid carbon into a C-C bond to expand cyclobutanols to cyclopentanols

Yada, Akira,Fujita, Shoichiro,Murakami, Masahiro

supporting information, p. 7217 - 7220 (2014/06/09)

When a carbenoid species generated from a tosylhydrazone is reacted with a cyclobutanol in the presence of a chiral rhodium catalyst, a C-C single bond of the cyclobutanol is cleaved, and the carbenoid carbon is inserted therein to furnish a ring-expanded cyclopentanol in an enantioselective manner.
