The first example of a dearomative palladium-catalysed isocyanide insertion reaction has been developed using functionalized isocyanides as the reaction partner of N-(2-bromobenzoyl)indoles. The imidoyl-palladium intermediate generated by tandem indole double bond/isocyanide insertion reactions could be trapped by intramolecular functional groups such as the C(sp2)-H bond and alkenes, affording diversified
approach for the synthesis of indane-based α-amino acid derivatives is reported. In this regard, the synthesis of five-membered exocyclic and five-membered inner-outer ring diene building blocks (7 and 15) containing α-amino acid moieties is described. Diene 15 is prepared by an enyne metathesis reaction as a key step. In this paper, a full account of our work regarding the Diels-Alderreaction of these dienes

Abstract γ-Thiolactams were synthesized in good yields from ethyl isocyanoacetate through a sequential alkylation/isothiocyanation/radical cyclization under microwave irradiation.
Enantioenriched 2-azabicyclo[3.1.0]hexanes are accessed from readily available allyl substituted α-isocyanoesters by intramolecular (1 + 2) cycloaddition with the olefinic moiety and isocyano carbon as the respective C2 and C1 units. Cyclopropanation is initiated by 1,1-hydrocupration of isocyanide followed by formimidoylcopper to copper α-aminocarbenoid equilibration and subsequent (1 + 2) cycloaddition
Synthesis of a diene building block via enyne metathesis reaction and its usage in the preparation of constrained alpha-amino acid derivatives is described. (C) 1998 Elsevier Science Ltd. All rights reserved.
