Beschreibung

Benzyl isocyanate, is used as a protected ammonia equivalent in the stereo selective ring-opening of chiral 2,3-epoxy alcohols (from Sharpless asymmetric epoxidation). The key step in the sequence involves intramolecular cyclization of the carbamate intermediate. It is also used in a multicomponent, stereospecific synthesis of 1,3-oxazinane-2,4-diones employing an Al-salph complex.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Benzylisocyanat wird als geschütztes Ammoniakäquivalent in der stereo-selektiven Ringöffnung chiraler2,3-Epoxidalkohole (aus der asymmetrischen Sharpless-Epoxidation) verwendet. Der entscheidende Schritt in der Sequenz besteht in der intramolekularen Zyklisierung des Carbamat-Zwischenprodukts. Es wird auch in einer multikomponentigen, stereospezifischen Synthese von1,3-oxazinan-2,4-Dionen mit einem Al-salph-Komplex verwendet.

Löslichkeit
Es hydrolysiert mit Wasser.

Hinweise
