1907-1998. If the abstract is located on more than one page, all the relevant pages are automatically downloaded.
(9) SCAN must be specified on the command line, i.e., D SCAN or DISPLAY SCAN.
(10) The RNK and RNKM formats display only the hit term occurrence ranking for the record, with the following line:
RELEVANCE SCORE ##. RNK is for the single file environment, while RNKM is for the multifile environment.

CIII. - A new synthesis of phloroglucinol

AB Recent researches in the terpene series, and especially investigations into the natureof camphor, have led to the development of various formulae to represent the constitutionof the latter. Especially prominent within the last few years have been the formulae
proposed by Tiemann and others, in which camphor is represented as containing two
variously substituted pentamethylene rings, which have three carbon atoms in common. The
proposed formulae may also be described as consisting of a substituted hexamethylene ringin which two carbon atoms in the para position are united by single bonds to a seventhcarbon atom. At the suggestion of the late Professor Victor Meyer, the author madevarious experiments with a view to the synthesis of a substance of analogous
constitution. Although, unfortunately, the end in view was not attained, the experiments
resulted in a new synthesis of phloroglucinol from ethylic acetonedicarboxylate, and thus
added another to the many known methods of passing from the fatty to the aromatic series.
Phloroglucinol itself has already been prepared synthetically from another member of thefatty series by Baeyer (Ber., 1885, 18, 3457) who, by heating the monosodium derivativeof ethylic malonate, obtained the ethylic salt of phloroglucinoltricarboxylic acid. The
ethereal salt, when melted with potash, yielded phloroglucinol.
