, p. 819 - 822 (2007)
2,3,5,8-Tetrahydroxy-1,4-naphthoquinone (spinazarin) and 6-ethyl-2,3,5,8-tetrahydroxy-1,4-naphthoquinone (ethylspinazarin) were first isolated from the sea urchin Scaphechinus mirabilis. The structures of spinazarins were established based on analysis of spectroscopic data. A preparative synthetic route to ethylspinazarin was proposed.

Several potentially bis(alkylating) bis(quinones) (3-5) and 1,4- and 1,3-bis(alkylating) monoquinones (6-13) belonging to general structure 2,2'-ethylenebis[5-[(leaving group) methyl]-1,4-benzoquinone] (3-5) and 2,5- and 2,6-bis[(leaving group)methyl]-1,4

A homologous series of 4 alkyl 2,5 dimethoxyphenylisopropylamines (alkyl = H through n C5H11 and t C4H9) was synthesized and compared with mescaline as serotonin agonists in a sheep umbilical preparation. The three carbon homolog 6d was found to be the most potent of the straight chain series in accordance with its observed psychotomimetic effectiveness in man.
