概要

• 論文の詳細を見る

• Use of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in boiling xylene was found to be a convenient method for the retro-cycloaddition of adducts of 4-phenyl-1,2,4-triazolidine-3,5-dione (PTAD) with steroidal 5,7-dienes. This process was applied to the syntheses of ergosta-5,7,24(28)-trien-3β-ol and ergosta-5,7,22,24(28)-tetraen-3β-ol.
