Syntheses of highly functionalised 6-substituted pteridines.
Methods for the synthesis of polyfunctional 6-substituted pteridines from the corresponding 6-aldehydes are described. Alkene, ester, ketone, amide, cyano, oxime, bromo, methoxy and dihydroxy functional groups have all been introduced principally through improved methodologies for Wittig reactions using 2-thioalkyl-6-formylpteridines as substrates. Further modification of the alkenes derived fr...
متن کامل6 beta-hydroxycortisol in serum and urine as determined by enzyme immunoassay on microtitre plates.
We modified our previous enzyme immunoassay (Clin Chim Acta 1986;157:267-76) for estimating 6 beta-hydroxycortisol (6 beta-OHF) to provide a more routine procedure for measuring it in urine and to increase sensitivity for its measurement in serum. Precision, analytical recovery, specificity, and detection limit are reported. 6 beta-OHF and 17-hydroxycorticosteroids in 24-h and 4-h (08:00-12:00 ...
متن کاملSyntheses and applications of furanyl-functionalised 2,2’:6’,2’’-terpyridines
Different synthetic routes leading to terpyridines functionalised with furan heterocycles are reviewed. The methodologies used to prepare such compounds include the ring closure of 1,5-diketones and cross-coupling reactions. These versatile terpyridines and their derived metal complexes find applications in various fields including coordination chemistry, medicinal chemistry and material sciences.
متن کاملSyntheses and photophysical properties of 5'-6-locked fluorescent nucleosides.
Nine fluorescent 5'-6-locked nucleosides were synthesized by condensation of various 1,2-diketones with 5-amino-2'-deoxycytidine. The nucleosides have different substituents on the pyrazine core structure, ranging from two methyl groups to polyaromatic rings. The photophysical properties of each nucleoside were determined, with the nucleosides displaying diverse absorption and emission maxima, ...
متن کاملSyntheses and Structure of 8-, 7-, and 6-Membered Silacycloallenes
Decreasing the ring size of a cyclic allene to rings of fewer than 10 carbons results in deviation of both the normal C=C=C linearity and the orthogonality of the dihedral angle.' To date, the smallest isolable cycloallene is 1-tert-butyl-1,2-cyclooctadiene,2 and the smallest for which structural information is available is the phenylurethane derivative of cyclonona-2,3-dien-1-oJ,l which is ben...
