General description

1-Bromopinacolone is an α-bromoketone-aldehyde. Coupling of 1-bromopinacolone with various aldehyde electrophiles catalyzed by SmI2 has been reported. It acts as reversible competitive inhibitor for acetylcholinesterase, during hydrolysis of acetylcholine.

Application

1-Bromopinacolone is the suitable reagent for the synthesis of a photolabile azido derivative of the kaurene oxidase inhibitor 1-(4- chlorophenyl)4,4-dimethyl-2-(1,2,4-triazol-1-yl) pentan-3-ol (paclobutrazol). It may be used as reagent in the synthesis of 2-t-butyl-6-benzoylimidazo[1,2-b]pyridazine.

Highly substituted, very hindered enones were synthesized using a two-step procedure that utilizes a diiodosamarium-promoted Reformatsky-type coupling and dehydration using Martin sulfurane. Both alpha-chloro- and alpha-bromoketones were coupled with a variety of carbonyl nucleophiles to form the intermediate beta-hydroxyketones, occurring

1-Bromo-2-[14C]pinacolone, (CH3)3C14COCH2Br [( 14C]BrPin), was prepared from [1-14C]acetyl chloride and tert-butylmagnesium chloride with cuprous chloride catalyst, followed by bromination. It was examined as an active-site directed label for acetylcholinesterase (acetylcholine acetylhydrolase, EC 3.1.1.7) (AcChE). AcChE, isolated from Torpedo nobiliana, has
