Benzothiazines in organic synthesis. An approach to floresolide B
摘要:
The intramolecular conjugate addition of a sulfoximine carbanion to an alpha,beta-unsaturated ester results in the formation of a benzothiaine bearing a benzylic stereocenter with extremely high fidelity. We have used this methodology to complete a formal total synthesis of the antitumor agent (+)-floresolide B. (C) 2011 Elsevier Ltd. All rights reserved.
