DETAILS

Description (English)

Application
The bulky isopropyl groups (vs. ethyl) allow for more selective reductions, e.g., beta-selective reduction of anomeric C-phenyl ketals, but do not diminish their activity (e.g. in the copper triflate catalyzed reductive etherification of trimethylsilyl ethers).
Used in a highly diastereoelective preparation of anti-1,2-diols catalyzed by a Ni(O) N-heterocyclic carbene complex.1
Packaging
10 g in glass bottle
50, 250 g in Sure/Seal™

Description (简体中文)

Application
大体积异丙基（与乙基相比）能实现选择性更高的还原反应（例如，异头 C-苯基缩酮的 β-选择性还原），但是不会降低它们的活性（例如，三甲基硅醚的三氟甲烷磺酸酮催化型还原醚化）。
用于 Ni(O) N-杂环卡宾络合物催化的反式-1,2-二醇的高度非对映选择性制备。1
