AN APPROACH TO THE A RING OF VITAMIN D ANALOGUES VIA SEQUENTIAL CARBOMETALATION/ ANION CAPTURE
An intramolecular palladium catalysed carbometalation followed by anion capture achieves construction of a model comprised of the A ring of Vitamin D oxygen analogues.
متن کاملInheritance of a ring 14 chromosome.
A family is described in which the mother, her two live offspring, and a therapeutically aborted fetus each had a ring 14 chromosomes. The two children were mentally retarded and the mother's intelligence was at the lower end of the normal range. In addition, the mother had two spontaneous abortions, one of which was shown to be chromosomally normal.
متن کاملRegioselectivity and tautomerism of novel five-membered ring nitrogen heterocycles formed via cyclocondensation of acylthiosemicarbazides.
A series of 1-acyl-4-phenyl/(acridin-9-yl)thiosemicarbazides 3, including four new compounds, were prepared in order to study substituent effects on cyclization reactions with oxalyl chloride (producing imidazolidine-4,5-diones 4), dimethyl acetylenedicarboxylate (to give thiazolidin-4-ones 7 and 8) and autocondensation under alkaline conditions (to yield 1,2,4-triazoles 9). A positional isomer...

متن کاملa case of autism with ring chromosome 14.
autism is a complex neuropsychiatric disorder that manifests in early childhood. although the etiology is unknown yet but, new hypothesis focused on identifying the key genes related to autism may elucidate its etiology. the main objective of the present study was to verify the value of karyotyping in autistic children and identifying association between chromosome abnormalities and autism.we e...
