A New Method for Cleaving Carbohydrate Triphenylmethyl and Benzyl EthersCarbohydrate triphenylmethyl and benzyl ethers are converted into their trimethylsilyl ethers by iodotrimethylsilane. The silyl ethers are hydrolysed to give partially free sugars. From multiple benzylated glycosides it is possible to remove selectively the primary benzyl group, under more vigorous conditions total debenzylation occurs.
Notes:
Mit Iodtrimethylsilan werden Kohlenhydrat-triphenylmethyl- und -benzylether zu Trimethylsilyl-ethern umgeethert, die zu den entsprechenden partiell freien Zuckern hydrolysiert werden. In mehrfach benzylierten Glycosiden läßt sich selektiv der primäre Ether spalten, unter drastischeren Bedingungen tritt vollständige Debenzylierung ein.
