Lewis base directed cycloaddition reactions of 2-pyrones and alkynylaluminum reagents
Crepin, Damien F.,Harrity, Joseph P. A.
, p. 4222 - 4225 (2013)
In situ generated alkynylaluminum reagents have been utilized in a [4 + 2] cycloaddition with 2-pyrones bearing a Lewis basic donor. The reactions proceed at or below room temperature and with complete regiocontrol. This one-pot method affords diversely s
