Iridium-catalyzed selective N-allylation of hydrazines
Matunas, Robert,Lai, Amy J.,Lee, Chulbom
, p. 6298 - 6308 (2007/10/03)
A highly chemo- and regioselective iridium-catalyzed allylic amination is described. The reaction of various hydrazones and hydrazides with allylic carbonates proceeds at ambient temperature in the presence of an [Ir(COD)Cl]2/pyridine catalyst,
Synthesis of azapeptides from hindered amines leading to novel growth hormone secretagogues
Hansen, Thomas Kruse
, p. 9119 - 9120 (2007/10/03)
Preparations of aza analogues of known potent growth hormone secretagogues (GHS) were unsuccessful using known methods for preparation of azapeptides when hindered amines were employed. We now report a coupling method using bispentafluorophenylcarbonate as a 'balanced reactivity' phosgene equivalent to solve these problems.
