- Competitive formation of β-amino acids, propenoic, and ylidenemalonic acids by the Rodionov reaction from malonic acid, aldehydes, and ammonium acetate in alcoholic medium
-
The Rodionov reaction of 49 available aliphatic and aromatic aldehydes with malonic acid and ammonium acetate in alcoholic medium, resulting in formation of β-amino acids, propenoic, and ylidenemalonic acids, was studied. Certain regioselectivity regularities of the reaction were revealed. Among the variety of ketones studied, cyclohexanone is the only whose reaction yields a β-amino acid. Unusual dehydrofluorination of 6-chloro-2-fluorocinnamic acid under the Rodionov reaction was discovered. 2005 Pleiades Publishing, Inc.

- Juvenile hormone mimics
-
Insect populations are controlled by treating an immature form of the insect with a novel compound possessing juvenile hormone-like activity. Such a compound is one having the formula EQU1 wherein Y is thienyl, phenyl or substituted phenyl. For example, 9-(3,4-methylenedioxyphenyl)-2,6-dimethyl-2,6-nonadiene exhibits very good activity.
