CAS 112022-83-0: (R)-2-Metil-CBS-ossazaborolidina

Descrizione:
(R)-2-Metil-CBS-ossazaborolidina è un composto organoboro chirale che funge da catalizzatore in varie reazioni di sintesi asimmetrica, in particolare nella formazione di legami carbonio-carbonio. Questo composto presenta un atomo di boro coordinato a una struttura di oxazaborolidina, che contribuisce alla sua reattività e selettività uniche nella catalisi. La presenza del gruppo metile nella posizione 2 migliora le sue proprietà steriche ed elettroniche, rendendolo efficace per reazioni enantioselettive. La sua natura chirale gli consente di favorire preferenzialmente la formazione di un enantiomero rispetto all'altro, il che è cruciale nella sintesi di prodotti farmaceutici e altri prodotti chimici fini. Il composto è tipicamente utilizzato in reazioni come la riduzione di chetoni e aldeidi, dove può facilitare la formazione di alcoli con un alto eccesso enantiomerico. Inoltre, (R)-2-Metil-CBS-ossazaborolidina è apprezzato per la sua stabilità e facilità di manipolazione, rendendolo una scelta popolare nella chimica organica sintetica. Le sue applicazioni si estendono a vari campi, inclusa la chimica medicinale e la scienza dei materiali, dove la chiralità gioca un ruolo significativo nelle proprietà e nelle attività dei composti risultanti.

  • (R) -2-Methyl-CBS-oxazaborolidine - 1M solution in Toluene

    CAS:
    (R) -2-Methyl-CBS-oxazaborolidine is a chiral, optically pure 2-methyl-CBS oxazaborolidine. It has been used as a reagent for the stereoselective synthesis of aldehydes. The (R)-2-methyl CBS-oxazaborolidine is prepared by the reaction of the corresponding boronic acid with hydrocyanic acid in toluene. The (S)-2-methyl CBS-oxazaborolidine can be obtained from the reaction of (S)-CBS with hydrocyanic acid in toluene. A high yield of product is obtained from this reaction, and it is an efficient way to synthesize aldehydes such as maxacalcitol, which are not readily available commercially.
