In order to prepare intermediate c-3, chlorosulfonic acid (3890 g; 33.3 mol) was stirred under nitrogen. Then intermediate c-2 (1288 g; 7.80 mol) was added portionwise maintaining the internal temperature below 60C by external cooling. After complete addition of intermediate b-2 the reaction mixture was stirred overnight at 85C. The heating was removed and the reaction mixture was cooled down until 65C. SOC12 was added dropwise while maintaining a controlled release of gases by good stirring. This mixture was stirred overnight at 65C. This reaction mixture was added to a well stirred mixture of EtOAc (6.9 kg) and ice (9.2kg) while maintained the temperature below 0C. The organic layer was isolated. The aqueous phase was extracted with EtOAc (3.1 KG). The combined organic layer was washed with 7.5 % NAHC03 (210 g/2.8 L water). Because the pH of this water layer was still 1, therefore another 125 g NAHC03 was added. This mixture was stirred for 1 hour, then the phases were separated. The organic layer was dried with NA2C03 (2.5 kg). After filtration 1935 g of intermediate c-3 was obtained (yield 94%, HPLC purity 94%) and used in the preparation of compound c-6.

(b) 6-Bromo-2-(methylthio)benzoxazole 2-(Methylthio)benzoxazole (5.8 g, see (a) above) was dissolved in chloroform (75 ml) and a solution of bromine (6.0 g) in chloroform (30 ml) was added dropwise, with stirring, over a period of 45 minutes. The mixture was allowed to stand overnight at room temperature and the solvent removed by distillation under reduced pressure to give a brown oil. The oil was washed with aqueous sodium metabisulfite and crystallized from ethanol/water to give the title compound as pink platelets (2.0 g), mp 95-96 C.

Oxa-Michael Addition to alpha,beta-Unsaturated Nitriles: An Expedient Route to gamma-Amino Alcohols and Derivatives

Water addition to alpha,beta-unsaturated nitriles would give facile access to the beta-hydroxy-nitriles, which in turn can be hydrogenated to the gamma-amino alcohols. We have previously shown that alcohols readily add in 1,4-fashion to these substrates using Milstein’s Ru(PNN) pincer complex as catalyst. However, attempted water addition to alpha,beta-unsaturated nitriles gave the 3-hydroxynitriles in mediocre yields. On the other hand, addition of benzyl alcohol proceeded in excellent yields for a variety of beta-substituted unsaturated nitriles. Subsequent treatment of the benzyl alcohol addition products with TMSCl/FeCl3 resulted in the formation of 3-hydroxy-alkylnitriles. The 3-benzyloxy-alkylnitriles obtained from oxa-Michael addition also could be hydrogenated directly in the presence of acid to give the amino alcohols as their HCl salts in excellent yields. Hydrogenation under neutral conditions gave a mixture of the secondary and tertiary amines. Hydrogenation in the presence of base and Boc-anhydride gave the orthogonally bis-protected amino alcohols, in which the benzyl ether can subsequently be cleaved to yield Boc-protected amino alcohols. Thus, a variety of molecular scaffolds with a 1,3-relationship between O- and N-functional group is accessible starting from oxa-Michael addition of benzyl alcohol to alpha,beta-unsaturated nitriles.
