The first enantioselective total synthesis of 10-isocyano-4-cadinene, a marine sesquiterpene isolated from nudibranchs of the family Phyllidiidae, and determination of its absolute stereochemistry were achieved. 10-Isocyano-4-cadinene is expected to be a novel nontoxic antifouling agent. In the synthesis, intermolecular Diels-Alder reaction and samarium diiodide induced Barbier-type cyclization were employed as key steps. The absolute configuration of 10-isocyano-4-cadinene was determined as (1S,6S,7R,10S) by comparison of the optical rotations between natural and synthetic samples. In addition, the authors successfully synthesized 10-epi- and di-1,6-epi-10-isocyano-4-cadinene through the same synthetic pathway. Antifouling activities against Balanus amphitrite with the cadinenes were also evaluated.

A novel synthesis of the renin inhibitor aliskiren based on an unprecedented disconnection between C5 and C6 was developed, in which the C5 carbon acts as a nucleophile and the amino group is introduced by a Curtius rearrangement, which follows a simultaneous stereocontrolled generation of the C4 and C5 stereogenic centers by an asymmetric hydrogenation. Operational simplicity, step economy, and a good overall yield makes this synthesis amenable to manufacture on scale.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 189028-95-3, name is (S)-3-((S)-5-(4-Fluorophenyl)-5-hydroxypentanoyl)-4-phenyloxazolidin-2-one, introducing its new discovery. Product Details of 189028-95-3

The S alcohol in the benzylic position of compound 2, a key feature of a novel cholesterol lowering agent Ezetimibe, was introduced by the (R)-MeCBS catalyzed asymmetric carbonyl reduction of ketone 1 using borane tetrahydrofuran complex (BTHF) as the reducing agent. The chemo- and enantioselectivity was dramatically enhanced by using an acid as a scavenger of the stabilizer sodium borohydride present in the commercially supplied pure BTHF. The effect of the critical reaction parameters such as addition mode of reagent, temperature, acids as well as water content on the selectivity has been examined. This reaction has been successfully applied in the commercial process for the preparation of the key intermediate 2 for Ezetimibe.

Militarinone C and fumosorinone A, 3-oligoenoyltetramic acids produced by insect pathogenic fungi, were synthesized for the first time. The pyrrolidine-2,4-dione ring was closed through a late-stage Dieckmann condensation of N-(beta-ketoacyl) derivatives of tyrosine, obtained by its acylation with either thioesters or Meldrum’s acid derivatives bearing the all-trans-polyene side chain. The latter was built up from (S)-citronellol via an Evans methylation and Wittig or HWE olefinations.

A series of 4-amino cyclohexanes and 4-substituted piperidines were prepared and evaluated for inhibition of DPP-4. Analog 20q displayed both good DPP-4 potency and selectivity against other proteases, while derivative 20k displayed long half life and modest oral bioavailability in rat. The most potent analog, 3-(5-aminocarbonylpyridyl piperidine 53j, displayed excellent DPP-4 activity with good selectivity versus other proline enzymes.
