Enantioselective allylation of thiophene-2-carbaldehyde [PDF]
, 2012 The first part of the bachelor thesis deals with enantioselective allylation of thiophene-2- carbaldehyde to the corresponding chiral homoallylic alcohol by using chiral Lewis bases as catalysts. The highest asymmetric induction achieved was 97 % ee. The

Inherent directing group enabled, Co(III)-catalyzed C-H allylation/ vi-nylation of isoquinolones [PDF]
The site-selective C8-allylation and vinylation of isoquinolones have been accomplished using allyl acetate and vinyl acetate and oxo group of isoquinolone as an inherent directing group in the presence of Co(III) catalysis. A plausible mechanism for the
