Hydrozirconation of functionalized alkyne 8 in CH2C32 with the Schwartz reagent followed by in situ transmetallation to Me2Zn and addition of N-diphenyl-phosphinoylimine 15 provides the functionalized trans-aminocydopropane 16 in 60% yield [15]. The cydopropane formation can be rationalized by the formation of a transient zinc-carbenoid species from CH2CI2, which subjected the intermediate allylic amine derivative to an efficient Simmons-Smith-type cydopropanation. [Pg.509]
