Enantioselective allylation of imines catalyzed by newly developed (-)-β-pinene-based π-allylpalladium catalyst: an efficient synthesis of (R)-α-propylpiperonylamine and (R)-pipecolic acid was written by Fernandes, Rodney A.;Nallasivam, Jothi L.. And the article was included in Organic & Biomolecular Chemistry in 2012.Computed Properties of C23H26BrP This article mentions the following:
A newly developed π-allylpalladium with a (-)-β-pinene framework and an iso-Bu side chain catalyzed the enantioselective allylation of imines in good yields and enantioselectivities (20 examples, up to 98% ee). An efficient enantioselective synthesis of the (R)-α-Pr piperonylamine part of a human leukocyte elastase inhibitor and (R)-pipecolic acid have been achieved as a useful application of this methodol. In the experiment, the researchers used many compounds, for example, Isopentyltriphenylphosphonium bromide (cas: 28322-40-9Computed Properties of C23H26BrP).
Isopentyltriphenylphosphonium bromide (cas: 28322-40-9) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Computed Properties of C23H26BrP
