A [3+3] cyclization strategy for asymmetric synthesis of alkyl substituted piperidine-2-ones using 1,2-cyclic sulfamidates: A formal synthesis of (S)-coniine from l-norvaline

Regioselective ring-opening reactions of a set of representative 1,2-cyclic sulfamidates with lithium triethylorthopropiolate proceeded efficiently to deliver the corresponding δ-amino-α,β-unsaturated esters after acidic hydrolysis. Hydrogenation of the unsaturated esters and subsequent thermal cyclization afforded the related alkyl substituted piperidine-2-ones. This approach represents a novel [3+3] cyclization strategy for the asymmetric synthesis of alkyl substituted piperidin-2-ones. Efficiency of the cyclization process is illustrated by a formal asymmetric synthesis of (S)-coniine from l-norvaline.

PNU-286607 is the first member of a promising, novel class of antibacterial agents that act by inhibiting bacterial DNA gyrase, a target of clinical significance. Importantly, PNU-286607 displays little cross-resistance with marketed antibacterial agents and is active against methicillin-resistant staphylococcus aureus (MRSA) and fluoroquinoline-resistant bacterial strains. Despite the apparent stereochemical complexity of this unique spirocyclic arbituric acid compound, the racemic core is accessible by a two-step route employing a relatively obscure rearrangement of vinyl anilines, known in the literature as the "tert-amino effect." After a full investigation of the stereochemical course of the racemic reaction, starting with the meso cis-dimethylmorpholine, a practical asymmetric variant of this process was developed.
