A new and efficient one-pot synthesis of 2,5-dihydrofurans from propargyloxiranes and arylboronic acids takes advantage of sequential rhodium-gold catalysis. The transformation proceeds with center-to-axis-to-center chirality transfer and tolerates a

Two methods involving the rhodium-catalyzed reaction of 2-en-4-yne acetates and the palladium-catalyzed reaction of 2-en-4-yne carbonates with organoboronic acids were investigated; both afforded exclusively the (E)-configured vinylallenes. The coord
