Methane monooxygenase catalyzed oxygenation of 1,1-dimethylcyclopropane. Evidence for radical and carbocationic intermediates.
3-Methyl-3-buten-1-ol is a rearrangement product that can be rationalized on the basis that enzymatic oxygenation of 1,1-dimethylcyclopropane proceeds via the (1-methylcyclopropyl)carbinyl radical, which is expected to undergo rearrangements with ring opening to the homoallylic 3-methyl-3 toen- 1-yl radical in competition with conventional oxygenation.

Effects of sulfur-containing analogues of stearic acid on growth and fatty acid biosynthesis in the protozoan Crithidia fasciculata.
A variety of analogues of stearic acid in which one of the methylene groups was replaced by a sulfur atom were examined as inhibitors of growth and fatty acid biosynthesis in the trypanosomatid protozoan Crithidia fasciculata to find effects similar to those of the fatty acids from which they were derived.

Reactions of 3-ethylcatechol and 3-(methylthio)catechol with catechol dioxygenases.
Analysis of the products of the reactions showed that ring cleavage occurs in a normal fashion between carbons 2 and 3 of the alternate substrates, and 3-(methylthio)catechol is a very poor substrate for catechol 1,2-dioxygenase, but it is a potent competitive inhibitor. Expand
