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.
新型α-炔基和α-CF3氨基酯已从电亲核亚胺合成,并用于通过与前催化剂[RuCCCPh2(Cl)(PCy3)(arene)]O3SCF3的炔烯复分解反应生成3-烯基-3,4-脱氢脯氨酸衍生物。这些新的含氟共轭二烯是Diels–Alder反应的活性底物,并导致一种新的双环氨基酯类别的形成。
