- Alkylbenzoquinone involved in development of cellular slime molds
-
The structure of the prespore-cell-promoting factor from Dictyostelium discoideum was determined to be 2-hydroxy-5-methyl-6-pentylbenzoquinone. The synthetic compound has prespore-cell-promoting activity similar to the natural one, with half-maximal induction at a concentration as low as 40 pM. It was also found that the factor induces aggregation in an aggregation-deficient mutant of a related species, Polysphodilium violaceum. Both these activities are sensitive to positional isomerism with the 6-methyl-5-pentyl isomer showing no detectable activity.

- Metalation reactions. XVI. Polylithiation of 1,3,5- and 1,2,4-trimethoxybenzene
-
Polylithiation reactions of 1,3,5- and 1,2,4-trimethoxybenzenes have been investigated. Results showed that it is possible to substitute all arylic hydrogens through one-pot sequential bimetalation/monometalation, monometalation/bimetalation or three mono
