Synthesis of novel 1α,25-dihydroxy-19-norvitamin D3 with an amide conjugate

The diene system of 1α,25-dihydroxy-19-norvitamin D3 was replaced by a stable amide bond. A 3-hydroxypropoxy group, which was effective on enhancing binding affinity of 1α,25-dihydroxyvitamin D3 for vitamin D receptor (VDR), was introduced to the C2-position of the amide type analogue of 1α,25-dihydroxy-19-norvitamin D3. The amide analogue was found to be not suitable for binding to the ligand binding domain of the bovine thymus VDR, and additional modification at the C2-position did not improve the affinity. Potency in induction of HL-60 cell differentiation was evaluated for the novel amide analogues (3a-c).

De novo Synthesis of Carbohydrates and Related Natural Products, 34 Synthesis of N-Acetyl-β-D-neuraminic Acid Derivatives via Inverse-Type Hetero-Diels-Alder Reaction

Inverse-type hetero-Diels-Alder reaction-based diastereoselective synthesis of 3-deoxy-2-glyculosonates is performed with the help of chiral carbon substituents in the 2-position of the 1-oxa-1,3-diene required as heterodiene.This is demonstrated for the

Chiral Deuteration at C-5 of 1,5-Anhydropentofuranose Derivatives

Photobromination of 1,5-anhydropentofuranoses and subsequent metal deuteride reduction of the resulting 5-exo-bromides gave C-5 chirally deuterated 1,5-anhydropentofuranoses.The stereochemistry of the reduction is discussed in terms of the effects of substituents at C-2 and C-3 of 1,5-anhydropento-furanoses.
