Formal total syntheses of the (-)-salicylihalamides A and B from D-glucose and L-rhamnose

Two formal total syntheses of the (-)-salicylihalamides, based on chiral pool approaches, are reported. D-Glucose and L-rhamnose were used to prepare advanced intermediates 23 and 54, which can be converted in three or four steps, respectively, to the tar

Synthesis of stereospecifically labeled 3,6-dideoxyhexoses.

Preparations of ascarylose (3,6-dideoxy-L-arabino-hexose), abequose (3,6-dideoxy-D-xylo-hexose), and paratose (3,6-dideoxy-D-ribo-hexose) with stereospecific deuterium labeling at C-3 are discussed. The methods used to synthesize these sugars, such as the

SYNTHESIS OF STEREOSPECIFICALLY LABELED CARBOHYDRATES: PREPARATION OF (3S)- AND (3R)-ASCARYLOSE

The general problem of the synthesis of 3,6-dideoxy sugars containing stereospecifically labeled hydrogen isotope at C-3 is adressed for the specific case of ascarylose (3,6-dideoxy-L-arabino-hexose).

β-ELIMINATION IN ALDONOLACTONES. THE CONVERSION OF L-RHAMNONO-1,5-LACTONE INTO 3-BENZOYLOXY-6-METHYLPYRAN-2-ONE

Benzoylation of L-rhamnono-1,5-lactone (1) for 90 min at room temperature afforded 2,3,4-tri-O-benzoyl-L-rhamnono-1,5-lactone (2).When an excess of benzoyl chloride and pyridine was used for 20 h, with subsequent sublimation of benzoic acid from the mixture at 120 deg C in vacuo, a double elimination took place and 3-benzoyloxy-6-methylpyran-2-one (4) was isolated as the main product.The conversion of 1,2, and 2,4-di-O-benzoyl-3,6-dideoxy-L-erythro-hex-2-enono-1,5-lactone (3) into the pyran-4-one derivative 4 under different conditions was monitored chromatographically.
