A. Marchand et al., Oxazoline mediated routes to a unique amino-acid, 4-amino-13-carboxy[2.2]paracyclophane, of planar chirality, TETRAHEDRON, 56(37), 2000, pp. 7331-7338
Efficient syntheses leading to 4-amino-13-carboxy[2.2]paracyclophane and de
rivatives are described. Novel oxazolinyl[2.2]paracyclophanes are used as i
ntermediates and the oxazolinyl and amide groups are shown to be strong psi
-geminal directing groups. Compounds with potential as catalysts have been
made. (C) 2000 Elsevier Science Ltd. All rights reserved.
