S. Collina et al., On the enantiomers of 2-dimethylamino-3-pentanone, key intermediates in the synthesis of analgesic alkylaminoalkylnaphthalenes, TETRAHEDR-A, 10(12), 1999, pp. 2387-2397
2-Dimethylamino-3-pentanone 1 is the key intermediate in the synthesis of a
lkylaminoalkylnaphthalenic analgesics. In this paper the resolution of this
compound with L- and D-dibenzoyltartaric acids is described. The behavior
of the diastereomeric dibenzoyltartrates and of the enantiomers in solution
is investigated by NMR spectroscopy, polarimetry and chiral gas-chromatogr
aphic analysis. (C) 1999 Published by Elsevier Science Ltd. All rights rese
