Cyclic-fused azomethine-, imidate-, and thioimidate methylides: An efficient regiocontrolled entry into spiro-fused pyrrolidines
摘要:
Generation of azomethine ylides, imidate methylides, and thioimidate methylides which are exocyclic to indane, benzofuran, benzothiophene, and benzopyran moieties respectively, in the presence of electron deficient dipolarophiles, gives direct access to spiro-fused pyrrolidines in good yields and excellent regioselectivity.
