摘要:Probes comprising one or more selectively cleavable α-azidoether moieties are provided; and linkers comprising the one or more selectively cleavable α-azidoether moieties. The α-azidoether moiety will undergo a Staudinger reaction with a suitable reducing agent, resulting in cleavage. The probes find use in a variety of detection assays, e.g. specific polynucleotide binding assays, polypeptide binding assays, etc. The cleavable linkers are suitable for synthetic reactions, e.g. to prepare probes of the invention; in the synthesis of cleavable peptide conjugates; and the like.

摘要:A method for easily producing a heterogeneous catalyst having excellent catalytic activity at a low cost is provided. The heterogeneous catalyst is used for the purpose of synthesizing a cyclic carbonate by reacting an epoxide and carbon dioxide. A catalyst obtained by this production method and a method for synthesizing a cyclic carbonate with use of this catalyst are also provided.
