Asymmetric total synthesis of (+)-didemniserinolipid b via achmatowicz rearrangement/bicycloketalization

A new synthetic strategy was developed for the asymmetric total synthesis of (+)-didemniserinolipid B in 19 linear steps, featuring a highly efficient and enantioselective construction of 6,8-dioxabicyclo[3.2.1]octane (6,8-DOBCO) framework via a rarely explored Achmatowicz rearrangement/bicycloketalization strategy. In addition, the first total synthesis of the proposed (+)-didemniserinolipid C was accomplished with 41.6% yield in 4 steps from a common advanced intermediate 18, and a possible revised structure of (+)-didemniserinolipid C was proposed. The new convergent synthetic strategy greatly expedites the entry to the didemniserinolipids and their analogues for biological activity evaluation.

The discovery of long-acting saligenin beta2 adrenergic receptor agonists incorporating a urea group

A series of novel, potent and selective human beta2 adrenoceptor agonists incorporating a urea moiety on the terminal right-hand side phenyl ring of (R)-salmeterol is presented. Urea 9j had long duration of action in vitro on guinea pig trachea, and also in vivo similar to that of salmeterol. It had lower oral absorption and bioavailability than salmeterol in both rat and dog. It had a turnover ratio similar to salmeterol, with no evidence for formation of any aniline metabolites in human liver microsomes and hepatocytes. However no crystalline salts suitable for inhaled delivery were identified.

Total synthesis of “Aliskiren”: The first renin inhibitor in clinical practice for hypertension

We report a “macrocycle route” toward aliskiren, a drug presently marketed for the treatment of hypertension, using a highly stereocontrolled approach starting from a common “isopropyl chiron”. Highlights of the synthesis include a challenging RCM reaction to produce a nine-membered unsaturated lactone, a highly stereoselective catalytic Du Bois aziridination, and a regio- and diastereoselective aziridine ring-opening to a vicinal amino alcohol.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
