An Approach to the Synthesis of Stenine
Zhu, Liang,Lauchli, Ryan,Loo, Mandy,Shea, Kenneth J.
, p. 2269 - 2271 (2008/02/05)
A type 2 N-acylnitroso intramolecular Diels-Alder reaction followed by reductive N - O bond cleavage formed the B and C rings of the Stemona alkaloid stenine. Further elaboration provided the functionalized tricyclic core.
Thiol esters in organic synthesis. X. A new approach to 1,5-ketols and 5-hydroxy esters using S,S'-diethyl dithiomalonate as an ethanol carbanion equivalent
Liu, Hsing-Jang,Oppong, Isaac V.
, p. 94 - 96 (2007/10/02)
Michael addition of S,S'-diethyl dithiomalonate to conjugated enones and α,β-unsaturated esters followed by reduction with Raney-nickel gave rise to 1,5-ketols and 5-hydroxy esters respectively in good yields.
