Acetal and ketal deprotection using montmorillonite K10: The first synthesis of syn-4,8-dioxatricyclo[5.1.0.03,5]-2,6-octanedione
摘要:
Montmorillonite K10 in dichloromethane at room temperature conveniently and efficiently converts acetals and ketals into the corresponding carbonyl compounds. The title dione (diepoxy-1-4-cyclohexanedione) has been prepared for the first time using this procedure. (C) 1997 Elsevier Science Ltd.
