Title (EN) VITAMIN D3 DERIVATIVES AND PROCESS FOR PRODUCING THE SAME
(FR) DERIVES DE VITAMINE D3 ET PROCEDE DE PRODUCTION
Abstract:
(EN) 1,25-Dihydroxy-2-methyl vitamin D3 derivatives represented by general formula (I) wherein R1 and R2 each independently represents hydrogen or tri(C1-7alkyl)silyl; and the asymmetric carbon atoms at the 1-, 2- and 3-positions each independently has an $g(a)- or $g(b)-configuration. These compounds are useful as remedies for osteoporosis, rachitis, accessory thyroidal hyperenergia, etc.
(FR) Cette invention concerne des dérivés de vitamine D3 1,25-dihydroxy-2-méthyle qui correspondent à la formule générale (I) où R1 et R2 représentent chacun indépendamment hydrogène ou tri(C1-7alkyl)silyle. Les atomes de carbone asymétriques aux positions 1-, 2- et 3- possèdent chacun et indépendamment une configuration $g(a) ou $g(b). Ces composés sont utiles en qualité de remèdes contre l'ostéoporose, le rachitisme, l'hyper-énergie thyroïdienne accessoire, etc.
