In 2007,Lotesta, Stephen D.; Hou, Yongquan; Williams, Lawrence J. published 《A Spirodiepoxide-Based Strategy to the A-B Ring System of Pectenotoxin 4》.Organic Letters published the findings.Quality Control of Methyl 3-hydroxypropanoate The information in the text is summarized as follows:
A synthesis of a pectenotoxin 4 C1-C15 segment is reported. Suitable C1-C7 I and C8-C15 II segments were prepared, coupled, converted to product III and the C3-hydroxy variant, and then cyclized. Key findings include the stereoselective conversion of the allene to the corresponding spirodiepoxide, oxidative cleavage of the p-methoxybenzyl ether, and cyclization of the spirodiepoxide to spiroketal IV. In the experimental materials used by the author, we found Methyl 3-hydroxypropanoate(cas: 6149-41-3Quality Control of Methyl 3-hydroxypropanoate)
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.
