Recent Claim

In solvolysis studies using Grunwald-Winstein plots, dispersions were observed for substrates with aromatic rings at the α-carbon. Several examples for the unimolecular solvolysis of monoaryl benzylic derivatives and related diaryl- or naphthyl-substituted derivatives have now been reported, where the application of the aromatic ring parameter (I) removes this dispersion. A recent claim suggesting the presence of an appreciable nucleophilic component to the I scale has now been shown, in a review of the solvolysis of highly-hindered alkyl halides, to be unlikely to be correct. Attention is now focused on the application of the hI term for the solvolysis of compounds containing a double bond in the vicinity of any developing carbocation. Available specific rates of solvolysis (plus some new values) at 25°C of cinnamyl chloride, cinnamyl bromide, cinnamoyl chloride, p-chlorocinnamoyl chloride, and p-nitrocinnamoyl chloride are analyzed using the simple and extended (including the hI term) Grunwald-Winstein equations.

The synthesis of 2-(E)-O-(4-hydroxy-cinnamoyl)-ᴅ,ʟ-galactaric acid (1a) is described. Starting with free galactaric acid (2) and 4-acetoxy-cinnamoyl-chloride (3), these compounds were esterified under regioselective conditions to racemic 2-(E)-O-(4-acetoxy-cinnamoyl)-galactaric acid (4). After deprotection of the p-coumaroyl moiety 1a was obtained as a photo-unstable product. Optical resolution of racemate l a on bovine serum albumin covalently bound to silica resulted in the isolation of the pure optical isomers. The (+)-dextrorotatory synthetic enantiomer l a proved to be identical with the natural factor.
