AN ELECTROCHEMICAL CHLORINATIVE ENE-TYPE REACTION OF ISOPRENOIDS
The chlorinative ene-type reaction of isoprenoids (12) has been performed by electrolysis in CH2Cl2-H2O-NaCl system.The reaction provides useful allylic chlorides 2 for terpene synthesis in high yields and is affected strikingly by the nature of halide ions and solvents. dl-Theaspirane 21 was prepared from α-dihydroionol via the electrolysis.
