A catalytic asymmetric hetero-Diels-Alder (HDA) reaction has been achieved through hydrogen-bond directed γ-addition of olefinic azlactones to isatins. This methodology provides an efficient access to spirooxindole dihydropyranones in moderate to good yie

The δ-opioid antagonist H-Tyr-Tic-Phe-Phe-OH (TIPP-OH) or its C- terminal amide analogue was systematically modified topologically by substitution of each amino acid residue by all stereoisomers of the corresponding β-methyl amino acid. The potency and se
