tert-Butyl 2-(difluoromethyl)-3-benzyl-6-methoxy-3,4-dihydro-4-quinazoline-4-carboxyl ic ester (4) and its related 6-substituted esters, precursors of a new type of cyclic amino acid, were synthesized via intramolecular defluorinative cyclization under basic conditions.

The methodology for the construction of β-trifluoromethyl-substituted isoserine is reported. The fluorinated α-hydroxy-β-imino esters which are the precursors to amino acid derived isoserine were formed firstly via a base catalyzed intramolecular rearrangement of imino ethers, and the subsequent conversions of these compounds resultedin the formation of the designedisoerines and the related fluorinated compounds.
... and radical 262 species (Figure 3). For example, the chloride 240a (X=Cl) can be used for M a n u s c r i p t nucleophilic substitution reactions with nucleophiles (Schemes 95-97) [112][113][114] or acid-catalyzed Friedel-Crafts reactions (Scheme 98) [115] to convert chlorine to other functional groups.
