A general and efficient protocol for the palladium-catalyzed functionalization of mono- and polyglycosyl thiols by using the palladacycle precatalyst G3-XantPhos was developed. The C-S bond-forming reaction was achieved rapidly at room temperature with various functionalized (hetero)aryl-, alkenyl-, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and anomer selectivities of thioglycosides are high in all cases studied. New sulfur nucleophiles such as thiophenols, alkythiols, and thioaminoacids (cysteine) were also successfully coupled to lead to the most general and practical method yet reported for the functionalization of thiols.

, p. 131 - 138 (2007/10/02)
A collection of aryl and alkyl 2-(trimethylsilyl)methyl sulfides have been converted to their respective sulfoxides by four different asymmetric oxidizing agents. The chemical yields range from 44-98% while the enantiomeric excesses range from 0-89%. The
