Genome cyclization as strategy for flavivirus RNA replication
(Elsevier Science, 2008-09)
Long-range and local RNA-RNA contacts in viral RNA genomes result in tertiary structures that modulate the function of enhancers, promoters, and silencers during translation, RNA replication, and encapsidation. In the case ...
Cascade cyclization triggered by imine formation. Formal synthesis of the alkaloid (±)-stemoamide and its 9a-epimer
(Elsevier, 2015-10)
A concise formal synthesis of stemoamide ( 1) and its 9a-epimer 14in 5 steps is described featuring a cas-cade cyclization triggered by imine formation. A good selectivity for either epimer is readily accom-plished by ...
Experimental and computational study of 6-exo and 7-endo cyclization of Aryl radicals followed by Tandem SRN1 substitution
(American Chemical Society, 2013-04)
The reaction of N-allyl-N-(2-halobenzyl)-acetamides and derivatives was investigated in liquid ammonia under irradiation with the nucleophiles Me3Sn−, Ph2P− and O2NCH2 −. Following this procedure, novel substituted 2- ...
