摘要: Abstract D -Mannose has been converted by six sequential reactions (acetonation, Wittig-intramolecular Michael reaction, selective deacetonation, glycol cleavage oxidation and Grignard reaction) into the methyl esters 9 10 which underwent a de-isopropylidenation reaction with concommitant lactonisation to give (3 S ,4 R )- ,7 )-diastereoisomers of goniofufurone 1 2 .
