The preparations of (Z)-α-phenoxymethylene-γ-butyrolactone, α-phenoxymethyl-γ-butyrolactone, (Z)-α-phenylthiomethylene-γ-butyrolactone, and α-phenylthiomethyl-γ-butyrolactone derivatives from 2-propynyloxy-benzene and 2-propynylthiobenzene were described.
Synthesis of alkylidenecyclopentenones and dialkylidenecyclopentenones via the coupling of propargylic alcohol and 2-alkyne-1,4-diol derivatives with cyclopropylcarbene-chromium complexes
