Reactivity of 2-acylaminoacrylates with ketene diethyl acetal; [2 + 2] cycloadditions vs. tandem condensations.

The reactivity of 2-acylaminoacrylates with ketene diethyl acetal can be modulated by means of thermal conditions to yield cyclobutanes for the preparation of protected beta-hydroxycyclobutane-alpha-amino acids, or catalytic conditions that yield cyclohexanes by tandem condensations to obtain interesting building blocks that are alternatives to Danishefsky's diene.

Erythromycin A 11,12-methylene acetal.

Erythromycin A 11,12-methylene acetal (5) and the corresponding 9-methoxime, 9-dihydro, and 8-hydroxy derivatives have been prepared and their antibacterial activities compared with those of erythromycin A and its 11,12-cyclic carbonate. The simple methylene acetal 5 showed excellent activity against Gram-positive organisms in vitro.

Synthesis of a Library of Propargylated and PEGylated α-Hydroxy Acids Toward “Clickable” Polylactides via Hydrolysis of Cyanohydrin Derivatives

A new simple and practical protocol for scalable synthesis of a novel library of propargylated and PEGylated α-hydroxy acids toward the preparation of "clickable" polylactides was described. The overall synthesis starting from readily available propargyl alcohol, bromoacetaldehyde diethyl acetal, and OEGs or PEGs was developed as a convenient procedure with low cost and no need of column chroma...

Studies of acetal phospholipides of brain. I. Procedure of isolation of crystallized acetal phospholipide from brain.

Feulgen and Rossenbeck (1) demonstrated in 1924 in the cytoplasm of cells the presence of substances which give histochemically a color reaction with Schiff’s aldehyde reagent. Feulgen and Voit (2) at the same time showed that the aldehyde group of these substances is not free, but bound in a labile form. The authors called this substance plasmalogen. Feulgen and Bersin (3) succeeded in 1939 in...
