Retro-1,4-cycloaddition of adducts derived from stereoidal 5,7-dienes and 4-phenyl-1,2,4-triazoline-3,5-dione
Abstract
1,4-Cycloadducts of various steroidal 5,7-dienes and 4-phenyl-1,2,4-triazoline-3,5-dione gave the corresponding steroidal 5,7-dienes in high yields when heated with organic bases at reflux for 15 min.
