Complex 5-C5H5)Fe(CO)2(η2-2-methylpropene)>+BF4- forms exchange complexes with the double bond in O-allyl group protected, O-benzylated sugar derivatives (6-14).From these compounds benzyl groups can be removed by catalytic hydrogenation.Decomplexation furnishes debenzylated, O-allyl groups containing products (15-22) in low to modest yields.Selective debenzylation, carbohydrates, η5-cyclopentadienyl-di(carbonyl)-η2-2-methylpropene-iron tetrafluoroborate
SYNTHETIC STUDIES ON NOGALAMYCIN: STEREOSPECIFIC C-5 ALKYLATION OF A SUGAR DERIVATIVE VIA CLAISEN REARRANGEMENT AND A NEW ROUTE TO 1,1,4-TRIALKOXYBUTA-1,3-DIENES.

Claisen rearrangement of the 4-methoxybutadienylether of the allylic alcohol 13 which was made in 15 steps from D-glucose, afforded one major aldehyde 17 or 18 in good yield.All attempts to oxidize to an acid were unsuccessful.The model compound 24 and compound 13, were converted respectively to the α, β-unsaturated esters 25 and 26.Compound 25 was further transformed into 1,1,4-trialkoxybuta-1,3-diene 27 which was found unreactive towards quinones.
