2-Thiazolyl alpha-amino ketones: A new class of reactive intermediates for the stereocontrolled synthesis of unusual amino acids

The thiazole-based one carbon homologation of four alpha-amino acids (L-phenylalanine, L-leucine, L-threonine, and L-serine) to the corresponding alpha-hydroxy beta-amino aldehydes and acids in both configurations at C(alpha), is described. The methodology involves the following key operations: (i) the conversion of an alpha-amino ester to a 2-thiazolyl alpha-amino ketone; (ii) the stereocontrolled reduction of a ketone carbonyl to either syn or anti alpha,beta-amino alcohols; (iii) the aldehyde release from the thiazole ring; (iv) the oxidation of the aldehyde to a carboxylic acid. The methodology was only partially applied to L-phenylglycine because of some limitations in operation (i).

Applications of the chiral auxiliaries DIOZ and TRIOZ for conjugate additions and comparison with other auxiliaries

A number of N-acryloyl-, N-crotonoyl-, N-(3,3,3-trifluorocrotonoyl)-, N-cinnamoyl-, and N-(3-nitroacryloyl)-4-isopropyl- or -4-phenyl-oxazolidin-2- ones with geminal diphenyl substitution, i.e., 7-15, have been prepared and used for conjugate additions of organocuprate reagents (Me, iPr, Ph, 4-MeOPh) in the beta-carbonyl (Table 2) and in the alpha-carbonyl position (NO2-derivative 11 in Scheme 3). The yields and diastereoselectivities are compared with previously tested enoyl-oxazolidinones (Table 2). Highest diastereoselectivities (>90%) are always observed with the 4-Ph derivatives (Hruby effect). Nitroacryloyl-oxazolidinones and a corresponding phenylmenthol ester undergo less diastereoselective additions (Scheme 3). A 3-(1-methylethyl)-5,5-diphenyloxazolidin-2-one (DIOZ)-derived Li2-enolatenitronate was also tested for alpha-carbonyl alkylation (Scheme 4). The X-ray crystal structures of three acryloyl-oxazolidinones and of four adducts are described (Tables 1 and 3), and they serve for configurational assignments and description of the stereochemical courses of the additions and alkylation. Possible applications of the nitro compounds for the preparation of beta2-amino acids are discussed (Scheme 2).

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

Lead optimization of 5-amino-6-(2,2-dimethyl-5-oxo-4-phenylpiperazin-1-yl)- 4-hydroxyhexanamides to reduce a cardiac safety issue: Discovery of DS-8108b, an orally active renin inhibitor

With the aim to address an undesired cardiac issue observed with our related compound in the recently disclosed novel series of renin inhibitors, further chemical modifications of this series were performed. Extensive structure-activity relationships studies as well as in vivo cardiac studies using the electrophysiology rat model led to the discovery of clinical candidate trans-adamantan-1-ol analogue 56 (DS-8108b) as a potent renin inhibitor with reduced potential cardiac risk. Oral administration of single doses of 3 and 10 mg/kg of 56 in cynomolgus monkeys pre-treated with furosemide led to significant reduction of mean arterial blood pressure for more than 12 h.
