Abstract
Highly selective coupling-cyclization of 3,4-allenols with aryl iodides via the oxidative addition-exo-mode oxypalladation-reductive elimination sequence afforded 2,3-dihydrofurans efficiently. The cyclization mode and the regioselectivity observed for 3,4-allenols are unique and different from what was reported previously.
Key words
