In 2004,Khokhar, Shaista S.; Wirth, Thomas published 《Nucleophile-selective selenocyclizations》.European Journal of Organic Chemistry published the findings.HPLC of Formula: 6149-41-3 The information in the text is summarized as follows:
Electrophilic cyclizations are one of the major strategies for cyclofunctionalizations of alkenes. Selective selenocyclizations can be performed by adjusting various factors in such reactions. The nature of the electrophile, the counterion, solvents, and external additives coordinating to the electrophilic species are used to control the course of such cyclizations with high degrees of efficiency. Investigations reported here have been extended towards stereoselective reactions using chiral selenium electrophiles. For example, the stereoselective selenocyclization of chiral selenium electrophile I with α-(hydroxymethyl)-γ-(methylene)benzenebutanoic acid (II) gave furanone III. In the experimental materials used by the author, we found Methyl 3-hydroxypropanoate(cas: 6149-41-3HPLC of Formula: 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. HPLC of Formula: 6149-41-3
