Mechanistic Insights into Electrooxidative Allylation of a Carbamate in the Presence of Solid-Supported Acids

open access: yesElectrochemistry
The electrooxidative allylation of a carbamate was successfully demonstrated using 3-propylsulfonic acid-functionalized silica gel (Si-SCX-2). It was shown that the electrochemical oxidation of the carbamate as a first step yields the corresponding N ...

Further exploration of the heterocyclic diversity accessible from the allylation chemistry of indigo

open access: yesBeilstein Journal of Organic Chemistry, 2015
Diversity-directed synthesis based on the cascade allylation chemistry of indigo, with its embedded 2,2’-diindolic core, has resulted in rapid access to new examples of the hydroxy-8a,13-dihydroazepino[1,2-a:3,4-b']diindol-14(8H)-one skeleton in up to 51%

One-pot synthesis of 5-amino-2,5-dihydro-1-benzoxepines: access to pharmacologically active heterocyclic scaffolds [PDF]

open access: yes, 2015
A one-pot multibond-forming process involving a thermally mediated Overman rearrangement and a ring closing metathesis reaction of allylic trichloroacetimidates bearing a 2-allyloxyaryl group has been developed for the synthesis of 5-amino-substituted 2 ...

Stereoselective synthesis of the published structure of synargentolide A and of one of its stereoisomers [PDF]

open access: yes, 2005
A stereoselective synthesis is described of the structure published for the naturally occurring synargentolide A, an α,β-unsaturated lactone. The key steps of the synthesis were a Brown´s asymmetric allylation and a ring closing metathesis.

Bi-mediated allylation of aldehydes in [bmim][Br]: a mechanistic investigation

open access: yesBeilstein Journal of Organic Chemistry, 2018
The inexpensive room temperature ionic liquid (RTIL), [bmim][Br] has been found to be a superior medium for the Bi-mediated Barbier-type allylation of aldehydes compared to other conventional solvents.

Indium-mediated allylation in carbohydrate synthesis: A short and efficient approach towards higher 2-acetamido-2-deoxy sugars

open access: yesBeilstein Journal of Organic Chemistry, 2014
Higher aminosugars are interesting targets in carbohydrate synthesis since these compounds play important roles in biological systems. However, their availability from natural sources is limited.
