WebAn efficient stereoselective approach to the tetracyclic core of Cryptotrione, involving an asymmetric Michael addition, ring-closing metathesis, and subsequent cyclopropanation, is described. WebThen he spent two more years postdoctoral research in the same group, in where he finished the total synthesis of Cryptotrione, and one year in the school of pharmacy in the same university. Maoyun joined the Brown group and is now working on metal-catalyzed alkene difunctionalization. In his free time, he enjoys staying with his family, hiking ...

WebCryptotrione ( 3 ), isolated from the Japanese cedar Cryptomeria japonica, showed activity against human oral epidermoid carcinoma KB cells. Henry N. C. Wong and Xiao-Shui Peng of the Chinese University of Hong Kong assembled the tetracyclic core 2 of 3 by the diastereoselective cyclization of the alkyne 1 ( Angew. Chem. Int. Ed. 2024, 59, 19929. WebThese nine cryptotrione family members share a structurally unprecedented skeleton that comprises spiro-annulation of abietane-type diterpene and thujane-type monoterpene. Web(Figure presented) A novel C 35-terpene, designated as cryptotrione (1), with an unprecedented skeleton possessing an abietane diterpene with a unique bicyclic sesquiterpene, is identified from the bark of Cryptomeria japonica.The carbon skeleton of 1 represents a new structural entity, and this is an intriguing addition to the structurally … how do you get ordained online
