The synthesis of various highly functionalized benzo-annulated indane-based α-amino acid (AAA) derivatives are reported via a [4+2] cycloaddition strategy using a sultine derivative, containing an AAA moiety, as a reactive diene component. By adopting this strategy, a new α,α-dialkylated indane-based C60 fullerene containing a constrained AAA unit is reported.
Indane-based peptides are biologically important compounds. Here, we carried out late stage modification of dipeptides containing 2-aminoindan-2-carboxylic acid (Aic) via Sonogashira coupling, [2+2+2] cyclotrimerization, sultine formation, Diels–Alder reaction and Suzuki–Miyaura cross coupling as key steps.

Synthesis of various benzo-annulated indane-based alpha-amino acid (AAA) derivatives are reported via a [4+2] and [2+2+2] cycloaddition reactions as key steps. Here, o-xylylene based AAA moiety has been used as a reactive intermediate and by adopting this strategy various indane-based constrained AAA derivatives are prepared. (C) 2004 Elsevier Ltd.
