Selective protection of the functionalities of α-hydroxy unsaturated aldehydes

The polyfunctionalized title compounds α-enol aldehydes are selectively protected either as ethylenic aldehyde acetates, ethylenic aldehyde sulfonates, ethylenic acetal sulfonates, or oxo acetal derivatives.

Kinetic and mechanistic studies on the rearrangement of 1-(substituted phenyl)-1,3-dimethoxy-2-propanones

The mechanism of rearrangement of 1-(substituted phenyl)-1,3-dimethoxy-2-propanones to give substituted benzylglyoxal dimethyl acetals (5) was studied by kinetic measurements, by the effects of acid catalysis, by rearrangements in the absence of acid and

A Study of Rearrangement of some 1,3-Dimethoxyalkan-2-ones

1,3-Dialkoxyacetones, 1-alkyl- and 1-(substituted phenyl)-, 1-alkanoyl-1,3-dimethoxyacetones, and methyl 2,4-dimethoxyacetoacetate were shown to undergo acid-catalysed rearrangement to give respectively methylglyoxal dialkyl acetals, 3-substituted methylglyoxal dimethyl acetals, 5-alkyl-3-methoxy- and 4,5-dimethoxyfuran-2(5H)-ones. 1-(Substituted aroyl)-1,3-dimethoxyacetones underwent only scission to give substituted ω-methoxyacetophenones.Methyl 2-alkyl-2,4-dimethoxyacetoacetates, 3- and 1-methoxy-, and 1,5-dimethoxypentane-2,4-diones were not affected by similaracid treatment except for the fact that they suffered some limited C-C bond scissions.Implications related to rearrangement mechanisms are discussed.
