Application

Aminomethyl allene was prepared by reaction of Boc propargyl amine with formaldehyde, diisopropylamine and copper bromide as part of a series of Bovine Plasma Amine Oxidase inactivators.
Protection of alcohols as Boc derivatives via Lewis acid catalysis.
Reagent for the introduction of the Boc protecting group.
Reagent for the preparation of Boc protected amines.
Tris-Boc protected hydrazine allows preparation of Fmoc ester in a chromophoric reagent to monitor solid-phase aldehydes.

Automated Boc protection and deprotection can be done using Synple Automated Synthesis Platform (SYNPLE-SC002), Boc protection cartridges ((SYNPLE-B001), (SYNPLE-B002), and Boc deprotection cartridges (SYNPLE-B011)

Warning

Hydrolyzes to t-butanol and CO2; causes internal pressure in bottle if exposed to moisture.

A direct method for quantifying solid-phase aldehydes has been developed, using a new reagent, 4-(9-fluorenylmethyloxycarbonyl)phenylhydrazine (FmPH). The FmPH reagent was synthesized in three steps (24% overall yield) from commercially available p-hydrazinobenzoic acid. Resin-bound aldehydes reacted quantitatively with FmPH, in the

Propargylic and activated allylic amines are known to inactivate the quinone-dependent plasma amine oxidases, possibly through active-site modification by the alpha,beta-unsaturated aldehyde turnover products. Although homopropargylamine (1-amino-3-butyne, 1) is a nonobvious candidate as a mechanism-based inhibitor, 1 was found to
