Direct synthesis of β-N-glycosides by the reductive glycosylation of azides with protected and native carbohydrate donors

A simple and straightforward method for the stereocontrolled synthesis of β-linked N-glycosides uses alkyl and aryl azides as the nitrogen source. The N-glycosides are formed in high yields and with high βselectivities (typically >70 % yield, >15:1 β:α selectivity). This approach is also amenable to the synthesis of N-glycosylated amino acids and peptides (see example, Fmoc=9-fluorenylmethoxycarbonyl). Copyright

Efficient synthesis of substituted oxopiperazines from amino acids

The synthesis of substituted oxopiperazines, which may act as conformationally constrained peptide mimics, is reported. The synthesis is based on the cyclization of sulfonamide dipeptides with dibromoethane as the 1,2-dielectrophile. Alternatively, these
