Product Details of 6149-41-3In 2019 ,《Synthesis of the Sex Pheromone of the Oleander Scale (Aspidiotus nerii)》 was published in Journal of Organic Chemistry. The article was written by Castaneda, Mary Montano; Bargues, Javier Marzo; Primo, Jaime; Fuertes, Ismael Navarro. The article contains the following contents:
A total synthesis of the oleander scale [Aspidiotus nerii (Bouche)] sex pheromone (I), the unique sesquiterpenoid containing a cyclobutane moiety of this class of compounds, has been developed. In order to implement this sex pheromone as a new environmentally friendly tool to manage this pest, a more cost-effective, multigram synthesis was required. This new synthetic route, having a Blaise reaction, iron-catalyzed carbon-carbon coupling, and [2 + 2] photocycloaddition reactions as key steps, provides a general access to 4-alkyl lactones as well as a robust access to the target sex pheromone. Starting from readily available compounds as 3-hydroxypropanenitrile, Et bromoacetate, and 2-acetylbutyrolactone, the synthetic sequence afforded the A. nerii sex pheromone with min. intermediate purification and good overall yield in nine linear steps. In the experimental materials used by the author, we found Methyl 3-hydroxypropanoate(cas: 6149-41-3Product Details of 6149-41-3)
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
