An S-alkyl-thioester-moiety-containing linker with an enhanced stability on a resin has been developed.A linker containing S-alkyl thioester with a spacer group, -CO-SC(CH3)2CH2CO-Nle-, was stable during the peptide chain elongation cycle.This thioester was stable under HF treatment conditions, and was rapidly activated by silver ions in the presence of N-hydroxysuccinimde (HONSu) to form a peptide bond.Using this linker, peptide segments covering the HU-type DNA-binding protein of Bacillus stearothermophilus (HBs), which was site-specifically labelled with 2H, 13C,and 15N, were prepared.Using these peptide segments, multi-labelled HBs was synthesized.Distinct signals of 2H, 13C, and 15N in HBs were detected by NMR spectrometry.

A wide variety of β-alkylthiocarboxylic acids are obtained by addition of alkanethiols - generated in situ from S,S-dialkyl dithiocarbonates - to appropriate α,β-unsaturated carboxylic acids in good to excellent yields.

The stereoselectivity of the reactions of 2-acyl- and 2-aroyl-4,4,6-trimethyl-1,3-oxathianes and -4,6,6-trimethyl-1,3-oxathianes with organometallic reagents has been studied as a function of the following reaction variables: substitution pattern (4,4,6 o
