Facile and Efficient Synthesis of Dendrimers and One-Pot Preparation of Dendritic–Linear Polymer Conjugates via a Single Chemistry: Utilization of Kinetically Selective Thiol–Michael Addition Reactions
We present the first xanthate surface functional dendrimers which undergo rapid one-pot deprotection to thiols and subsequent acrylate Michael addition .
A convenient method for synthesizing 3-amino-1,5-benzodiazepine-2-one via the Michael addition reaction of o-phenylenediamine with dehydroalanine ester derivatives, followed by cyclization, was developed. This simple method was used to obtain a variety of N-substituted 3-amino-1,5-benzodiazepine-2-ones in one pot with good yields.
A tin-catalyzed solvent free one-pot multi-component cascade reaction strategy for the efficient synthesis of β-azaarene substituted ketones via an aldol–Michael addition/C(sp3)–H functionalization of 2-alkylazaarenes has been developed.
A simple and efficient synthesis of Hagen's gland lactones was achieved using a sequential α-aminoxylation/oxa-Michael approach in a highly diastereoselective manner with assignment of relative configurations.
