Decarboxylative hydrazination of unactivated carboxylic acids by cerium photocatalysis
We report the cerium photocatalyzed radical decarboxylative hydrazination of carboxylic acids with di-tert-butylazodicarboxylate (DBAD). The operationally simple protocol provides rapid access to synthetically useful hydrazine derivatives and overcomes current scope limitations in the photoredox-catalyzed decarboxylation of carboxylic acids.
Synthesis of N-propargylphenelzine and analogues as neuroprotective agents
A series of N1- and N2-propargylphenelzine derivatives and analogues (1-7) was synthesized. In addition to their activity as monoamine oxidase inhibitors, two of the compounds, N1- and N2-propargylphenelzines (3 and 6), were found to be potent at preventing DSP-4-induced noradrenaline (NA) depletion in mouse hippocampus, suggesting that they have neuroprotective properties.

N-tert-butoxycarbonylaminophthalimide, a versatile reagent for the conversion of alcohols into alkylated tert-butylcarbazates or hydrazines via the Mitsunobu protocol
An efficient two-step method has been developed for the conversion of alcohols to substituted hydrazines. The use of N-tert- butoxycarbonylaminophthalimide as an acid partner in Mitsunobu reactions with a variety of alcohols permits the synthesis of the corresponding monoalkylated tert-butylcarbazates and hydrazines.
