Detritylation什么意思
WebSep 19, 2007 · An efficient, high-yielding Lewis acid promoted deprotection of O-trityl hydroxylamine derivatives is described. A range of acid-labile protecting groups, such as N-Boc and O-TBS, were tolerated under these mild conditions. The present method is applicable to the synthesis of a broad range of hydroxylamine derivatives, including N … WebThe detritylation reaction is complex 125b, 132 and the amount of acid needed depends on the type of support used and increases with the ON chain length and is therefore not constant. The trityl cation generated during detritylation has an intense yellow/orange color, and it has been used to determine the end point of the detritylation reaction ...
