A description is given of the synthesis of a-hydroxypropiovanillone, a possible precursor of
lignin, and of its behavior toward diazomethane and theGrignard reagent.

On the basis of the postu-lated8 origin of vitamin Ki in nature it seemed likely that this
substance might be obtainable by the direct condensation of phytol with a 2-alkyl-l, 4-naph-…

… Fry: I think that Gropius is a good man in a sense. I regard him as a George Stevenson, full

2, 5, 9-Trimethyl-6, 7-benzomorphan (VIII) has been synthesized from 3, 4-lutidine methiodide
(V) and benzylmagnesium chloride or from/3-tetralone, while the hydroxy derivative (X) …

Base took more than two-minutes heating on the steam-bath. Since hydrolysis and
formation of the ß-haloalkylamideinvolve anionic attack on positions two and five, a high …

Bond tautomerism of 2-benzyl-l, 3, 4-trimethyl-l, 2-dihydropyridine salts, controlled by salt
form and solvent conditions, leads to cis-andirans-forms of 2-benzyl-l, 3, 4-trimethyl-2.3-…

Sodium borohydride under ordinary conditions has not proved useful for the reduction of l-(2-indol-3-ylethyl)
