Stereoselective Michael-alkylation and Michael-oxidation reactions of chiral 1,3-dioxolanones
摘要:
A highly diastereoselective Michael-alkylation/oxidation methodology has been developed for the synthesis of optically active alpha-hydroxy-1,5-diester subunits. Inverse stereochemistry at the C-2' position could be achieved by using a Michael acceptor equipped with a suitable group followed by a highly stereoselective protonation. This methodology has been applied to the enantioselective synthesis of the upper fragment of (+)-retusine. (C) 2017 Elsevier Ltd. All rights reserved.
and transitionmetal-free conditions, a series of functionalized N-alkylated sulfonamides were prepared. This protocol also enabled the functionalization of pharmaceutical drugs bearing a sulfonamide or carboxylic acid moiety. This radical-mediated process allowed the assembly of three components including sulfonamides, redox active esters, and alkenes to yield complex sulfonamides in a one-pot manner
