TY  - JOUR
AB  - Kinetic profiling has shown that a (DHQD)2PHAL catalysed intermolecular asymmetric alkene bromoesterification reaction is inhibited by primary amides, imides, hydantoins and secondary cyclic amides, which are by-products of common stoichiometric bromenium ion sources. Two approaches to resolving the inhibition are presented enabling the (DHQD)2PHAL loading to be dropped from 10 to 1 mol% while maintaining high bromoester conversions over short reaction times. Iterative post-reaction recrystallisations enabled a homochiral bromonaphthoate ester to be synthesised using only 1 mol% (DHQD)2PHAL.
