摘要:Synthesis techniques are described for forming organotin trialkoxide compounds via direct alkylation of tin alkoxides. A first method involves reacting an alkali metal tin trialkoxide with an organohalide compound (RXn, where X is a halide atom and n≥1) to form a monoorgano tin trialkoxide represented by the formula R[Sn(OR′)3]n. The method can be used to form polytin trialkoxide compounds with a plurality of radiation sensitive C—Sn bonds. R and R′ include organo groups and can optionally comprise hetero-atoms and/or unsaturated bonds. A second method involves the ultraviolet light-driven reaction of a di-tin tetraalkoxide with an organohalide compound (RX) to form a monoorgano trialkoxide represented by the formula RSn(OR′)3. A third method involves the visible or ultraviolet light-driven reaction of a di-tin tetraalkoxide or an alkali metal tin trialkoxide with an fluorinated organohalide compound (RFX) to form a fluorinated monoorgano trialkoxide represented by the formula RFSn(OR′)3. The disclosed methods provide for high mono-organo specificity. Corresponding organotin trialkoxide compositions are also described. The compositions are useful for radiation patterning, especially with EUV radiation. The organotin trialkoxide compositions may be formed as radiation-patternable coatings on substrates.

摘要:The invention relates to methods for selectively converting a cysteine residue in a peptide or protein to the dehydroalanine (Dha) residue. The method also works on selenocysteine and substituted cysteine and selenocysteine residues, resulting in the Dha residue which may be converted to any natural or unnatural amino acid residue desired without the alteration of the remainder of the peptide or protein. The invention also allows ligation of a desired peptide at any point rather than at a point where there should be a naturally occurring cysteine, thereby allowing native chemical ligation to be used in the synthesis of peptides that do not contain cysteine. The methodology allows for the synthesis of very large peptides.
