According to previous studies, short-day (SD) treatment may increase frost hardiness in Picea abies (L.) Karst. seedlings during shoot elongation the next year. The purpose of this study was to examine how timing of the SD treatment affects spring fr

Addition of aluminium oxide to boiling pyridine solutions of d -xylose, l -arabinose, d -mannose and d -glucose strongly increased the reaction rate of the aldose–ketose transformation. The maximum content of 2-ketose was reached after less than 2

A method for analysis of mixtures of 3-hexuloses by gas chromatography mass spectrometry of their di- O -isopropylidene derivatives has been elaborated. The origin of characteristic fragment ions in the mass spectra is suggested on the basis of the s

—The reaction rate of the Lobry de Bruyn–Alberda van Ekenstein transformation of aldoses to ketoses in boiling pyridinewas strongly increased by the addition of aluminium oxide. In addition to aldose–ketose transformation, 2-epimers of the star

Base-catalysed isomerisation of aldoses of the arabino and lyxo series in aluminate solution has been investigated. l -Arabinose and d -galactose give l - erythro -2-pentulose ( l -ribulose) and d - lyxo -2-hexulose ( d -tagatose), respectively, in g

A simple, but low-yielding method for the synthesis of 3-hexuloses has been elaborated. Oxidation of 1,2:5,6-di-O-isopropylidenehexitols with bromine in the presence of barium carbonate, followed by mild-acid hydrolysis of the oxidation products gave

1,2-O-Isopropylidenealdohexofuranoses are oxidized by silver carbonate-Celite in boiling methanol to methyl 1,2-O-isopropylidenepentofuranuronates. 1,2-O-Isopropylidenepentodialdo-1,4-furanoses are intermediates, and various amounts of esters of 1,2-
