Tuning the reaction paths in palladium(0)-catalyzed coupling-cyclization reaction of beta-amino allenes with organic halides: a substituent switch.
[reaction: see text] Substituent effects on the allene moiety and the N-protecting group were found to be the dominant factor in determining the reaction paths in the Pd(0)-catalyzed coupling-cyclization reaction of beta-amino allenes with organic halides.
