Summary In the reaction of deoxyvasicinone with aldehydes, depending on the nature of the substituents of aromatic and heterocyclic aldehydes, and also on the reaction conditions, 9-benzylidene or 9--hydroxybenzyl derivatives of deoxyvasicinone are obtained.Institute of the Chemistry of Plant Substances, Academy of Science of the Uzbek SSR, Tashkent.

Summary RS-Abscisic acid and some of its analogs have been obtained. The biological activity of these compounds has been studied in dependence on their structure.It was found that precursors of RS-abscisic acid suppress the growth of segments of coleoptiles to a considerably smaller extent than the acid itself.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

It is shown that the addition of aniline proceeds at the carbon-carbon double bond of N-acryloyl-, N-chloroacryloyl-, and N-methylacryloylbenzoxazolones. The basicity of the amine has a substantial effect on the course of the reaction with various amines. Transamidation of the acryloyl residue occurs with strongly basic amines.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1044–1048, August, 1974. 相似文献

The elasticity moduli and absorption coefficients of longitudinal ultrasonic waves with a frequency of 2–50 MHz depending
on the steel concentration and sintering temperature of 1400–1700°C in vacuum were studied in samples of cermet-type composites
on the basis of corundum and stainless steel. The results were discussed from the point of view of the elastic waves propagating
in the fine-disperse two-phase medium at the presence of the intergrain and interphase boundaries, noticeably affecting the
physical properties of the composite. 相似文献
