WebA copper-catalysed regio- and stereoselective hydroamination of acrylates with hydrosilanes and hydroxylamines has been developed to afford the corresponding α-amino acids in good yields. The key to regioselectivity control is the use of hydroxylamine as an umpolung, electrophilic amination reagent. Addition WebIn Friedel–Crafts reactions with electron rich aromatic rings, the chiral α-chloro-α-thiophenylacetate ester 172 was shown to give good diastereoselectivity (Scheme 34). 53 The ester 173 was prepared by reaction of phenylthioacetic acid chloride 174 with (−)-8-phenylmenthol 149 in the presence of pyridine in benzene at 0 °C. sports cards calgary
