Synthesis and testing of 2alpha-modified 1alpha,25-dihydroxyvitamin D(3) analogues with a double side chain: marked cell differentiation activity.

The 2alpha-methyl-, 2alpha-(3-hydroxypropyl)-, and 2alpha-(3-hydroxypropoxy)-derivatives of the 'double side chain' analogue of 1alpha,25-dihydroxyvitamin D(3) were synthesized using Trost A-ring/CD-ring connective strategy. Regarding the requisite A-ring building blocks, a new, high yield and stereoselective route to the 2alpha-methyl compound starting from D-glucose was developed. All three new analogues showed potent HL-60 cancer cell differentiation activity.

Synthesis of A-ring synthon of 2α-substituted vitamin d3 analogues utilizing Grignard reaction towards methyl 2,3-anhydro-4,6-o-benzylidene-α-D-manno-pyranoside

A concise route to the Trost A-ring precursor enyne for synthesizing 2α-substituted 1α,25-dihydroxyvitamin D3 (1) is described, in which the 2α-substituents could be introduced via addition reaction of Grignard reagent towards the sugar epoxide

REVISION OF THE ASSIGNMENT OF RELATIVE STEREOCHEMISTRY IN SIBIROSAMINE: SYNTHESIS OF METHYL N-TOSYL α-D-SIBIROSAMINOPYRANOSIDE

A synthesis of the N-toluenesulfonamide of α-methyl D-sibirosaminopyranoside has resulted in a reassignment of the relative stereochemistry of sibirosamine, a rare sugar found as its glycoside in sibiromycin.
