A novel axially chiral spiro-phosphine-catalyzed highly regio-, diastereo- and enantioselective [3+2] cycloaddition of alkylidene azlactones with various allenic esters has been developed, affording the corresponding functionalized spirocyclic products in

Phosphines go one-pot: The one-pot synthesis of cyclic α-amino esters from azlactones and allenes by a phosphine-catalyzed [3+2]-cycloaddition reaction followed by a ring opening of the azlactone moiety is presented. The products are isolated as single re
