Combination of tert-butoxycarbonyl and triphenylphosphonium protecting groups in the synthesis of substituted hydrazines

(matrix presented) A new reagent for the systematic synthesis of substituted hydrazines is reported. Unlike previously developed reagents, this one contains only two protecting groups, thus providing a faster approach to multisubstituted derivatives. The selective introduction of alkyl and acyl groups is illustrated by a few examples. Also a new fast method for the deprotection of the triphenylphosphonium group is presented.
