Solvent-Free Mechanochemical Deprotection of N-Boc Group
Boc protection group could be readily removed in a very mild mechanochemical conditions. In a short reaction time, ball milling of Boc-protected amines with p-toluenesulfonic acid in solvent-free conditions affords corresponding amine p-TsOH salts.
متن کاملBoiling water-catalyzed neutral and selective N-Boc deprotection.
A general protocol for removing Boc groups from various types of nitrogen is reported and a preliminary investigation of the reaction mechanism indicates that water acts as a dual acid/base catalyst at elevated temperature.
متن کاملOn the rearrangement of N-aryl-N-Boc-phosphoramidates to N-Boc-protected o-aminoarylphosphonates
Abstract Various arylamines were converted in two steps to N-Boc-N-arylphosphoramidates. LiTMP and LDA induced directed ortho-metalation at temperatures from -78 to 0 °C. The ensuing [1,3]-migration of the phosphorus atom with its substituents from the nitrogen to the ortho-carbanionic carbon atom gave N-Boc-protected o-aminoarylphosphonates. The nature of the substituent of 3-substituted pheny...
متن کاملNew Unambiguous Boc(n,n) Tracking Technique
Galileo and Modernized GPS have included in their signal structures a new signal modulation: the Binary Offset Carrier (BOC). In the navigation field, this modulation is characterized by the chipping rate of its spreading code (m×1.023 MHz) and the frequency of its square sub-carrier (n×1.023 MHz). As a consequence, it is usually referred to as a BOC(n,m) modulation. The choice of the parameter...
متن کاملJitter Analysis of QPSK and BOC(n,n) GNSS Signals
This paper analyzes the effects of jitter on the GPS and Galileo navigation signals. Jitter effects have usually been modelled as additive noise, based on a sinusoidal input signal, and limits the achievable Signal-to-Noise Ratio (SNR). Analysis shows that psec-level jitter specifications are required in order to keep jitter noise well below the thermal noise for software radio satellite naviga...
