Reaction Steps
The sulfinimine-mediated asymmetric synthesis involves addition of ethylaluminium cyanoisopropoxide generated in situ by addition of isopropanol (i-PrOH) to diethylaluminium cyanide (Et2AlCN) to the compound VIIa. Thus treatment of compound VIIa (1.0 mmol) at −78° C. in THF with 1.5/1.0 equiv of Et2AlCN/i-PrOH gave amino nitrile VIII in good yield (50-70%).
