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. 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
