2 7-Di(tert-butyl)-9-fluorenylmethyl Usage And Synthesis
Uses2,7-Di-tert-butyl-9-fluorenylmethyl chloroformate may be used in the preparation of polymer-supported (2,7-di-tert-butyl-9-fluorenyl)methyl succinimidyl carbonate (Dtb-Fmoc-P-OSu), a polymeric reagent for protecting amino groups.
General Description2,7-Di-tert-butyl-9-fluorenylmethyl chloroformate contains 2,7-di-tert-butyl-Fmoc protecting group (Fmoc= fluorenylmethoxycarbonyl), which is more soluble in organic solvents when compared to its Fmoc analog. It can be prepared from fluorene in three steps, by di-tert-butylation, hydroxymethylation and phosgenation.
