Popis: | Lithiated N-tert-butyldiphenylsilyl-S-methyl-S-phenylsulfoximine undergoes 1,2 addition to imines (R 1 CHNPh) and aldehydes (RCHO) to give diastereomeric adducts. The diastereoselection of the former reactions is dependent on the steric demand of the imine substituent R 1 , while that of the latter is independent of the steric demand of the aldehyde substituent R. |
