Protecting reagents are utilized to attach protecting groups to reactive functional groups in building blocks and intermediates to prevent unwanted side reactions, which are widely applied in organic reactions for producing peptides, sugars, nucleotides, terpenes, alkaloids and a large number of other chemicals.
J&K provides a wide range of protecting agents not only with conventional protecting groups (e.g. TMS, Boc, trityl), but also the novel ones like 1,2-bis(chlorodimethylsilyl)ethane (Cat. No.170393), which reacts only with aliphatic primary amines to generate azadisilacyclopentane derivatives.
