Exceptionally high trans (anti) stereoselectivities are obtained in rhodium(II) carboxylate and carboxamide catalyzed alkene cyclopropanation reactions with 2,6-di-tert-butyl-4-methylphenyl diazoacetate (BDA). With monosubstituted ethylenes, use of rhodiu

tert-Butyl and 2,6-di(tert-butyl)-4-methylphenyl (BHT) cyclopropanecarboxylates (4, 6, 24, 25) are lithiated with LiN(i-Pr)2 and t-BuLi, respectively.Reactions with alkyl halides, aldehydes, acyl chlorides, and heteroelectrophiles give α-substituted BHT esters which can be cleaved (t-BuOK/H2O/THF) to the corresponding carboxylic acids or reduced (LiAlH4/THF) to the cyclopropanemethanols.
