Download or read book Studies on the Total Synthesis of Tetrafibricin ; Synthesis of Conformationally Constrained Cysteine Protease Inhibitors ; Palladium Catalyzed Synthesis of N-aryl-2-benzylindolines Via Tandem Arylation of 2-allylaniline(s) written by Ricardo Lira and published by ProQuest. This book was released on 2008 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed in the following thesis are: (1) the diastereoselective synthesis of the C(1)-C(19) fragment of tetrafibricin, (2) a convenient, direct method for the synthesis 1,5-syn-(E)-diols from aldehyde precursors, and (3) application of this method to the completion of the C(23)-C(40) fragment of tetrafibricin (this transformation involves an initial allylboration generating syn-[beta]-alkoxyallylstannane intermediates, followed by an allylstannation step), (4) The synthesis of the complete C(1)-C(40) fragment via our double allylboration strategy and efforts towards the total synthesis of tetrafibricin, (5) the development of a convenient method to access syn-[beta]-hydroxyallylsilanes via a Lewis acid-promoted [gamma]-silylallylboration of alipathic aldehydes with new (Z)-[gamma]-silylallylboronate reagents, (6) The synthesis of a new class of conformationally constrained cysteine protease inhibitors via ring closing metathesis step, (7) a palladium-catalyzed synthesis of N-aryl-2-benzylindolines via a tandem arylation of 2-allylanilines, (this transformation leads to the formation of two C-N bonds and one C-C bond in a one-pot process, and high selectivity is observed for the sequential installation of two different aryl groups).
