Among the various phosphate/thiophosphate protecting groups suitable for solid-phase oligonucleotide synthesis, the 3-(N-tert-butylcarboxamido)-1-propyl group is one of the most convenient, as it can be readily removed, as needed, under thermolytic conditions at neutral pH. The deprotection reaction proceeds rapidly (t(1/2) approximately 100 s) through an intramolecular cyclodeesterification reaction
