The self-condensation of alkynals was for the first time implemented under mild organocatalytic conditions and was successfully linked with a domino organocatalytic inverse-electron-demand oxa-Diels-Alder reaction, which led to the development of a facile one-pot method to produce a wide variety of polysubstituted chiral 3,4-dihydropyrans with good to high yields and diastereoselectivities and ...
A synthetic route developed for the preparation of the A-ring of Taxol family of molecules is reported. By means of an intramolecular Diels-Alder reaction an asymmetric approach to this ring has been accomplished. Also, initial studies to prepare the A ring using an intramolecular Diels-Alder reaction have been successful.
The synthesis of silaheterocycles through the first examples of an intramolecular silene Diels-Alder reaction is described.
Leukocyte Adhesion Deficiency (LAD) is characterized by the inability of leukocytes, in particular neutrophilic granulocytes, to emigrate from the blood stream towards sites of inflammation. Infectious foci are nonpurulent and may eventually become necrotic because of abnormal wound healing. LAD-I is characterized by the absence of the beta-2 integrins CD II and CD 18 on leukocytes. We present ...
The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over las...
During the growth of five of ten primary tumors that were induced by 3-methylcholanthrene in BALB/cMk and BALB/cMk X C57BL/6F1 mice, leukemoid reactions, characterized by increase in number of granulocytes in peripheral blood, and splenomegaly were observed. However, no such reactions occurred in five C57BL/6 mice bearing primary tumors induced by 3-methylcholanthrene. The results of leukemoid ...
