Reaktionsschritte

A solution of 0.405 g (1.6 mmoles) of (S)-(+)-5-(3,4-dihydroxy-3-methyl-1-butyl)-2,3,6-trimethyl-p-benzoquinone in 20 ml of ethyl acetate was stirred in an atmosphere of hydrogen, in the presence of 0.04 g of 5% by weight palladium on 95% by weight charcoal until H2 uptake ceased (ca. 1 hr; 38 ml H2 absorbed). The catalyst was filtered and the filtrate was concentrated giving 0.41 g of (S)-5-(3,4-dihydroxy-3-methyl-1-butyl)-2,3,6-trimethylhydroquinone as a tan solid, mp 124°-131.5°.
