Abstract
Substituted γ-butyrolactones are important structural motifs in several natural products and pharmaceuticals. In this paper, we report the synthesis of novel γ-butyrolactone amine and thiazole derivatives from naturally occurring limonene. Regioselective bromination followed by nucleophilic substitution with different amines and thiourea gave desired products in moderate yield.
