Novel Base-Promoted Rearrangement of 2-(4-Cyano-, 2-Nitro-, and 4-Nitrobenzyloxy)tropones and 2-(2-Oxo-2-phenethyloxy)tropone to 2-[(4-Cyano-, 2-Nitro-, and 4-Nitrophenyl)hydroxymethyl]tropones and 2-(1-Hydroxy-2-oxo-2-phenethyl)tropone
Novel Base-Promoted Rearrangement of 2-(4-Cyano-, 2-Nitro-, and 4-Nitrobenzyloxy)tropones and 2-(2-Oxo-2-phenethyloxy)tropone to 2-[(4-Cyano-, 2-Nitro-, and 4-Nitrophenyl)hydroxymethyl]tropones and 2-(1-Hydroxy-2-oxo-2-phenethyl)tropone
The reaction of 2-chlorotropone with DIBAH followed by aldolization with several aldehydes affords 2-( l-hydroxyalkyl)tropones, subsequent oxidation of which results in the formation of 2-aroyl- and 2-acyltropones.
