WebThe first total synthesis of galanal A and B has been achieved from naturally occurring geraniol. Key steps in this synthesis are the use of a Lewis acid assisted chiral Brønsted acid (chiral LBA) mediated cationic polyene cyclization and a titanocene-mediated radical cyclization for the asymmetric assembly of the “AB” ring and the construction of the all … WebJun 20, 2012 · An efficient stereoselective approach to the tetracyclic core of Cryptotrione, involving an asymmetric Michael addition, ring-closing metathesis, and subsequent …
