Abstract

Investigations and stereoselective studies on the tandem reactions of carbonyl ylides generated from α-diazo ketones in the presence of carbonyl compounds are presented in this paper. Intramolecular cyclization of rhodium carbenoids generated the transient five-or six-membered-ring carbonyl ylide dipoles, which efficiently underwent 1, 3-dipolar cycloaddition reactions with various dipolarophiles such as aromatic aldehydes 15, α, β- ...
