study, a WNV NS2B–NS3 protease inhibitor with a 9,10‐dihydro‐3H,4aH‐1,3,9,10a‐tetraazaphenanthren‐4‐one scaffold was identified by screening a small library of non‐peptidic compounds. This initial hit was optimized by solution‐phase synthesis and screening of a focused library of compounds bearing this scaffold. This led to the identification of a novel, uncompetitive inhibitor (1a40, IC50=5.41±0.45 μM)

of molecular hybridization, a series of new isatin‐pomalidomide hybrids (9a–9g) were designed, synthesized, characterized, and evaluated for in vitro cytotoxic activity against U266B1 and RPMI 8226 multiple myeloma cell lines. Sandmeyer methodology and N‐halomethylketo alkylation reaction are the two important reactions involved in the synthesis of isatin‐pomalidomide hybrids (9a–9g). All the synthesized

A new isatin N,N′-cyclic azomethine imine synthon was devised, and an unexpected abnormal [3 + 2]-cycloaddition with maleimide catalyzed by 1,4-diazabicyclo[2.2.2]octane (DABCO) has been disclosed. A variety of tricyclic spiropyrrolidine oxindoles bearing a dinitrogen heterocycle and succinimide scaffold were obtained in excellent yields (up to 96%) and diastereoselectivities (up to 97:3) under mild
