A short, stereocontrolled synthesis of a key intermediate in the synthesis of thromboxane B2 is described. The approach is based on the use of N,N-diethyl(phenylsulfonyl)acetamide as nucleophile in a palladium-catalysed nucleophilic substitution reac

The reaction of methyl 2-(3-indolylmethyl)-acrylate 2 with carbethoxyformonitrile oxide 3, followed by saponification and reduction, gives mainly racemic monatin 1. Preliminary attempts to adapt the 2+3 cycloaddition to a new chiral synthesis of mona

The chiral synthesis of the fungal metabolite β- cyclopiazonic acid is described. The key step involves the use of the tricarbonylchromium complex of an N-protected L- tryptophan methyl ester as a substrate for the addition/oxidation method of subst
