A substituent controlled Claisen rearrangement is employed as the key reaction for a facile construction of chiral intermediates for the synthesis of pseudomonicacids from diacetyl-L-arabinal.

The pyran nucleus pseudomonic acid A has been prepared via a furan oxidation strategy. Introduction of the C-8 sidechain (pseudomonic acid numbering) was accomplished regio- and stereoselectively by either the Johnson variation of the Claisen rearrangement or by Pd-catalyzed allylic displacement.

second apparently similar Claisen rearrangement required significantly higher temperatures in all cases. Thus, similar hydroxy groups were differentiated without resort to selective protection. A stereoelectronic rationale based on the newly-introduced vinylogous anomeric effect (VAE) is put forth to explain the accelerated Claisen rearrangements of these glycals.
