A new amino protecting group, the methylsulfonylethyloxycarbonyl (Msc) group, is described which combines well with other familiar groups (benzyloxycarbonyl, t-butyloxycarbonyl) in peptide syntheses. Its main characteristics are an extreme acid stability, a high base lability and a high polarity which
