用途
用途
有機合成用試薬。
天然物の起源
benzyl isocyanate is a natural product found in Simicratea welwitschii with data available.
使用
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.
一般的な説明
Benzyl isocyanate inhibits the formation of benzo[a]pyrene (BP)-DNA adduct and posses chemopreventive properties.
