The first [4+2]-annulation between aminocyclobutanes and aldehydes to access tetrahydropyranyl amines is reported. With phthalimido cyclobutane dicarboxylates and aromatic aldehydes, tetrahydropyrans were obtained in 53-92% yield and 3:117:1 dr using scandium triflate or iron trichloride as catalyst. The use of thymineor fluorouracilsubstituted cyclobutanes gave direct access to six-membered ri...

We have adapted to RNA molecules the ligation-mediated polymerase chain reaction (LMPCR) procedure of genomic sequencing [Mueller, P. R. & Wold, B. (1989) Science 246, 780-786]. This new procedure, the reverse ligation-mediated PCR (RLPCR), is sufficiently sensitive to allow "in vivo" footprinting of minor RNA species. It is based on the ligation of an RNA linker of known sequence to every 5' e...

Anomalie d’émergence radiculaire par racine conjointe S1: à propos d'un cas

Nous rapportons le cas d'un patient âgé de 35 ans présentant une sciatique droite S1 hyperalgique rebelle aux multiples médications. L'IRM du rachis lombo-sacré avait mis en évidence une discopathi...
