Free Radical Cyclizations, Xvii. Mechanistic Studies
Free radical cyclizations of the 4-phenylbutyl radical and analogues carrying naphthyl and vinyl groups instead of phenyl have been studied. A typical reaction scheme is given below involving closures to fiveand six-membered rings. Competition rate studies for the various types of ring closure were performed with deuterated analogues. The results can be used as an efficient mechanistic tool for...

متن کاملStudies on Chemical Composition and Nutritive Evaluation of Wild Edible Mushrooms
Agaricus bisporus and Agaricus bitorquis are among most favorite mushrooms of the world. Mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. Na, K and Li contents were high, while Cr, Cu, Pb, Co, Zn, Mn and Ni concentrations were low in both Agaricus bisporus and Agaricus bitorquis. Proximate analysis showe...
متن کاملXvii. Neurology
Accommodation is most often seen in association with convergence, and it is well known that a variety of clues, particularly binocular fusion, drives convergence. Is there a monocular accommodation reflex, and if so, what is its stimulus? It is important to try to understand such a physiological error mechanism a widely distributed, unlearned, involuntary mechanism present in restricted monocul...
