Abstract

The cleavage requires longer reaction times when methoxy groups are present either ortho to nitro or ester moieties in place of carbonyl group. Further no cleavage was observed with anisole and di or trimethoxy benzenes. The deprotection was successful only with alkyl aryl ethers carrying formyl, acetyl and ester groups in the aromatic ring. The protocol could be success- fully applied for the selective removal of prenyl ethers present ortho to nitro, formyl, acetyl and ester ...
