Abstract

Spirolactones, spirotetrahydrofurans, and spiropyrrolidines containing a vicinal cis-diol adjacent to the spiro-carbon center are prepared by one-pot epoxidation/spirocyclization of cyclohex-2-en-1-ols bearing an ester, alcohol, or amide functional side chain at the C(3) position of the ring.
