A new synthetic approach toward (+)-ambruticin analogs: Preparation of a C10-C11 cis-isomer fragment

A new methodology has been applied to synthesize an isomer of the west part of (+)-ambruticin based on an efficient asymmetric de novo access to the A unit and sequential stereospecific reactions catalyzed by Pd0 for the construction of the B unit.

An improved dienophile-induced access to enantiopure 2,4-dideoxysugar lactones via hetero Diels-Alder reaction: Synthesis of the (+)-lactone moiety of compactin

Polystereocontrolled access to 4-type heterocycloadducts was consistently improved by using a new 4-oxy-substituted 1-oxabutadiene, methyl (E)-tert-butoxymethylenepyruvate (1c). Obtained in both enantiomeric forms with high diastereomerical purity, these adducts led to diprotected 2,4- dideoxyglucose 10 and -gluconolactone 12 in both L and D series in high yields. Epimerization of (-)-12 via intramolecular Mitsunobu inversion gave a straightforward access to the lactone moiety (+)-16 of compactin.

Chiral enol ethers in carbohydrate chemistry: De novo synthesis of protected L-2-deoxy hexoses

(3,4,6)Tri- and (3,4)-di-O-benzyl-2-deoxy-L-glucose 8 and 12 have been de novo synthesized in a convergent seven-step sequence involving asymmetric endo heterocycloaddition of the new heterodiene, methyl (E)-benzyloxymethylene pyruvate 2b with the O-vinyl mandelic ester (R)-(-)-3.
