Nepsilon 29, Nepsilon 59-Bis(methylsulfonylethoxycarbonyl)proinsulin was prepared from native beef proinsulin for its possible use in the semisynthesis of preproinsulin. The modification was made possible by first protecting the alpha-amino group of proinsulin either with the tert-butoxycarbonyl group, after reaction with

The precise estimation of the degree of derivatization of functional groups in polymers is important for determining their macroscopic properties. In this work, the quantitative estimation of the extent of esterification of novolac copolymers with di-tert-butyl dicarbonate was studied. Although

Perchloric acid adsorbed on silica-gel (HClO4-SiO2) was found to be a new, highly efficient, inexpensive and reusable catalyst for chemoselective N-tert-butoxycarbonylation of amines at room temperature and under solvent-free conditions.

We report a fundamentally unique approach to the catalytic kinetic resolution of amine derivatives based on formamide and thioformamide substrates. Readily accessible histidine-containing peptides mediate the kinetic resolutions with as little as 5 mol % catalyst. Selectivity factors (k(rel)) as

Total syntheses of two structures purported as (+)-heliananes were completed in six pots. Spectral comparisons, between the synthetic and natural compounds, revealed a misassignment of the eight-membered ring in the heliananes. The key step in the syntheses of the proposed
