  A facile method for deprotection of trityl ethers using column chromatography

  摘要：

  A mild, efficient and inexpensive detritylation method is reported that uses trifluoroacetic acid on a silica gel column to obtain pure, detritylated compounds in one-step. This method is applicable to acid stable as well as acid sensitive compounds with only slight alterations in the procedure. Nineteen examples are given. (C) 2001 Elsevier Science Ltd.
