M. Nagai et al., PRACTICAL TOTAL SYNTHESES OF (R)-(-14-HYDROXY-4,14-RETRO-RETINOL AND (S)-(-)-14-HYDROXY-4,14-RETRO-RETINOL()), Chemical and Pharmaceutical Bulletin, 42(7), 1994, pp. 1545-1547
Practical and facile total syntheses of the remarkably unstable (R)-()-14-hydroxy-4, 14-retroretinol [(R)-14HRR] 1 and of its enantiomer 2
have been achieved via an acid-catalyzed dehydration reaction of the r
espective tetraeneol intermediates 10 and its enantiomer obtained from
(R)-(+)-1,2-O-isopropylidene-butane-1, 2,3-triol 3.
