New α-alkynyl, α-CF3 amino esters have been prepared from electrophilic imines and used to produce 3-alkenyl-3,4-dehydroproline
derivatives, ia enyne metathesis with the precatalyst [RuCCCPh2(Cl)(PCy3)(arene)]O3SCF3.
These new conjugated fluorine-containing dienes
are active substrates for the DielsâAlder reaction and lead
to a new class of bicyclic
amino esters.
