The First Total Synthesis of(-)-Benzomalvin A via Intramolecular Aza-Wittig Reactions
The first total synthesis of (−)-benzomalvin A <B>1</B>, which possesses quinazolin-4(3<I>H</I>)-one moiety and 1,4-benzodiazepin-5-one moiety, was described. Both of 6- and 7-membered ring skeletons were efficiently constructed by intramolecular aza-Wittig reactions as the key reactions.
