Bei der Kondensation der Weinsaure und Schleimsaure mit o-Phenylendiamin kann man neben den bekannten Bisbenzimidazolylderivaten auch die bisher nicht beschriebenen Monobenzimidazolylderivate in guter Ausbeute bekommen.

Es wurden die Eigenschaften der in der Tschechoslowakei hergestellten Dextrane mit Hilfe der Perjodatoxydation und Methylierung studiert. Die Resultate, die durch Bestimmung der freiend-Fructose und des Molekulargewichtes erganzt worden waren, wurden zur Charakterisierung der Verzweigung der Dextrane benutzt.

The synthesis of ethyl-3,4,6-tri-O-benzyl-D-glucopyranoside and of ethyl-3,4,6-tri-O-benzyl-D-galactopyranoside is described. These compounds are isomers of ethyl-3,5,6-tri-O-benzyl-D-glucofuranoside, GLYVENOL®, a substance displaying interesting pharmacological actions.

Publisher Summary This chapter discusses the phthalideisoquinoline alkaloids. The term phthalideisoquinoline is applied to a group of eleven known alkaloids which are all derived from the parent substance I by the substitution of a hydroxyl or methoxyl a t position 8, and/or methoxyl and methylenedioxy groups at positions 6, 7, 4’, and 5’. Gnoscopine is dl-narcotine and has been isolated from opium, but, in view of the facile racernization of narcotine, there is the possibility that gnoscopine may be an artifact. The alkaloids narceine (VII) and hydroxynarcotine (nornarceine) (VIII) are derivable from narcotine by simple reactions and probably occur as such in opium, but they are not phthalideisoquinolines. With the exception of hydrastine, which has been found only in plants of the Ranunculaceae and Berberidaceae families, all of the phthalideisoquinolines have been found in plants of the Papaveraceae family.
