Mild Debenzylation of Aryl
Benzyl Ether with BCl3 in the Presence of Pentamethylbenzene
as a Non-Lewis-Basic Cation Scavenger
摘要:
Scope and limitations of the debenzylation conditions for aryl benzyl ether, which was developed during our synthetic studies on yatakemycin, were investigated. The chemoselective debenzylation proceeds at low temperature with a combination of BCl(3) and pentamethylbenzene as a cation scavenger in the presence of various functional groups.
