A series of p-nitroanilides of t-butyloxycarbonylamino acids, including Boc-Trp, Boc-Asn, Boc-Gln, Boc-Ser(But), Boc-Thr(But), Boc-Asp(OBut), Boc-Lys(TFA), and Boc-His(Boc), were prepared conveniently by the mixed anhydride method using 2,2-dimethylpropanoic chloride (pivaloyl chloride). The products were obtained in 40-60% yields after purification by

A series of methyl O-pivaloyl-alpha-D-mannopyranosides was synthesized using pivaloyl chloride in pyridine. The 3,6-di-O-pivaloyl derivative 6 undergoes intramolecular transesterification in neutral conditions (buffer, pH 7.2) to give its 2,6-di-O-pivaloyl analogue 5. The course of this migration was followed using 14C-labelled

A kinetic study on the reactions of pivaloyl chloride with a nucleoside H-phosphonate (bisacylphosphite formation), or a protected nucleoside with a free 5'-OH (5'-O-pivaloylation) has been carried out in the presence of differently substituted pyridines. The bisacylphosphite formation is a

Efficiency and stereoselectivity of condensations of ribonucleoside 3'-H-phosphonates with ethanol promoted by pivaloyl chloride were investigated as a function of tertiary amines used. Side reactions leading to an increased demand for the condensing agent were identified as derived from an
4'-pivaloyl substituted thymidine as a precursor for the thymyl radical: an EPR spectroscopic study.
