Web4,4′-Dimethoxytrityl tetrafluoroborate (DMT BF) and 4,4′,4″-trimethoxytrityl tetrafluoroborate (TMT BF) are useful reagents for protecting primary and some secondary amines. Protected amines are obtained either by reaction of DMT BF or TMT BF with the amine or by alkylating DMT- or TMT-amine (available from DMT BF Webthe synthesis of a novel β-C-nucleoside bearing a diol group at anomeric position, amenable as metal ligand or as organo-catalyst. The abasic ligand was successfully prepared and inserted into comple- ... The 5’-O was then functionalized with a 4,4’-dimethoxytrityl group (DMT), to give 14 in 60% yield. In turn, compound 14 was … tartan tights

WebJul 15, 2005 · Abstract. Removal of 4,4'-dimethoxytrityl (DMT) groups from primary and secondary hydroxyl functionality was investigated. It was observed that deblocking … WebMar 15, 2004 · This protecting group has since been used very widely indeed, especially in the solid phase synthesis of oligonucleotides and their analogues. 2 Twenty-five years … WebThe MIP group has been used, e.g., in solution-phase oligo-nucleotide synthesis for the primary 5’-hydroxy group of a nucleoside [7]. The acid lability of MIP is comparable to that of the dimethoxytrityl group (DMTr) that is frequently used to protect this position. The DMTr group works more or less tartan tip off brackets
