摘要:
A novel method of simultaneously protecting two functions which are same or different, namely hydroxyl, amine, or thiol ones, particularly in sugars, polyalcohols, nucleosides, nucleotides, peptides, and nucleic acids during an organic synthesis, and to novel compounds for implementing this method, as well as to the method of obtaining these compounds. Method of simultaneously protecting two hydroxyl, amine, or thiol functions according to the invention by carrying out a protecting reaction between a compound having at least two free hydroxyl, amine, or thiol groups, and the disilane of formula 1, where R stands for Cl or Br, or I, or a substituent of formula 2, where X1, X2, X3, X4 are the same or different.

摘要:
The present disclosure provides boron-containing diacylhydrazines having Formula I: and the pharmaceutically acceptable salts and solvates thereof, wherein R1, R2, R3, R4, and R5 are defined as set forth in the specification. The present disclosure also provides the use of boron-containing diacylhydrazines is ecdysone receptor-based inducible gene expression systems. Thus, the present disclosure is useful for applications such as gene therapy, treatment of disease, large scale production of proteins and antibodies, cell-based screening assays, functional genomics, proteomics, metabolomics, and regulation of traits in transgenic organisms, where control of gene expression levels is desirable.
摘要:
A (meth)allylsilane compound that a functional group of a (meth)allylsilyl group or a halogenosilyl group bonded to the (meth)allylsilyl group via a spacer group is bonded directly or through a divergent spacer group to a dehydrogenated residue of an amino group of an amino group-containing compound; a carbaminic acid ester group or an amide group derived from a dehydrogenated residue of the amino group; an aromatic compound; a polymerizable unsaturated groups; perfluoro group; a dehydrogenated residue of saccharide or a carbohydrate polyol (excluding when the divergent spacer group is an alkylene group, or an alkylene group and an arylene group); a dehydrogenated residue of an amino acid; a halogenosilyl group; or a substituted silyl group in which a halogen of the halogenosilyl group is substituted.
