Some specific areas discussed include polyester materials with low specific superficial electric resistance, the effect of organic and inorganic additives on the synthesis of lutetium silicates, similarity of zeolite micropore structures, new complex compounds of cobalt with cyanuric acid, frontal copolymerization of lactams, and oscillatory and spin regimes at frontal solidification of epoxy combinations in the flow.
Steroidal-4-en-3-ones such as 4-cholesten-3-one were treated with ozone to obtain a keto acid, 3,5-seco-4-norcholestan-5-on-3-oic acid (I), subsequently treated with amines to obtain enamine lactams which were discovered to react with Grignard reagents at elevated temperatures to yield novel unsaturated 3-alkyl derivativatives.
The focus then shifts to a systematic presentation of the various substrates classes, namely carboxylic esters, amides and peptides, lactams and lactones, esters of inorganic acids, alkene and arene epoxides, and some miscellaneous hydrolyzable moieties.
