A catalytic protocol for the enantio- and diastereoselective reduction of α-substituted-β-keto carbonitriles is described. The reaction involves a DKR-ATH process with the simultaneous construction of β-hydroxy carbonitrile scaffolds with two contiguous stereogenic centers. A wide range of α-substituted-β-keto carbonitriles were obtained in high yields (94%-98%) and excellent enantio- and diastereoselectivities (up to >99% ee, up to >99:1 dr). The origin of the diastereoselectivity was also rationalized by DFT calculations. Furthermore, this methodology offers rapid access to the pharmaceutical intermediates of Ipenoxazone and Tapentadol.

We demonstrated the synthesis of β-ketonitriles, α,β- alkynones, and biscarbinols using tert-butoxide-assisted C(CO)-C (i.e., acyl-C) coupling of esters under ambient conditions. tert-Butoxide-assisted C(CO)-C (i.e., acyl-C) coupling of esters with cyanomethylenes and acetylenes under transition metal-free ambient conditions gives β-ketonitriles, α,β-alkynones and/or aryl bis(phenylethynyl)carbinols in moderate-to-good yields. It is noteworthy that this is a rapid, facile, and efficient process under ambient conditions, and use of cheap and stable starting materials.
