“…Similarly, attempts to nitrate the dilithio derivative of cyclopropane carboxylic acid [22] or the enolate of the tert-butylthio ester [20] [21] failed. We found, however, that another lithiated cyclopropane carboxylate can be nitrated in good yield and can be used for reactions with electrophiles quite generally: the BHT ester 6 (see Scheme 6) which we have originally employed for in situ generation of cyclopropylidene ketene [25].…”
