Ring Expansion of Spirocyclic Dithioketals via 1,3-Sulfur Migration by the Mitsunobu Reaction
摘要:
Treatment of the spirocyclic dithioketals of some beta-hydroxy ketone derivatives with diisopropyl azodicarboxylate and triphenylphosphine furnished the ring-expanded products via 1,3-sulfur migration.
