Tkm. Shing et Hc. Tsui, ENANTIOSPECIFIC SYNTHESES OF (3S,4R)-DIASTEREOISOMER AND (3S,4R,7S)-DIASTEREOISOMER OF GONIOFUFURONE, Tetrahedron : asymmetry, 5(7), 1994, pp. 1269-1274
D-Mannose has been converted by six sequential reactions (acetonation,
Wittig-intramolecular Michael reaction, selective deacetonation, glyc
ol cleavage oxidation and Grignard reaction) into the methyl esters 9
and 10 which underwent a de-isopropylidenation reaction with concommit
ant lactonisation to give the (3S,4R)- and (3S,4R,7S)-diastereoisomers
of goniofufurone 1 and 2.
