[reaction: see text]. We have found that the 1,2-dihydroxylation of benzoic acid with Alcaligenes eutrophus strain B9, first reported in 1971 by Reiner and Hegeman, is readily adapted for the preparation of tens to hundreds of grams of (1S,2R)-1,2-dihydroxycyclohexa-3,5-diene-1-carboxylic acid of >95% ee. This unique substrate undergoes many specific oxidative and rearrangement processes. Among these
