(Z)-1,2:5,6-Di-O-isopropyl-idene-?-d-ribo-hexofuranos-3-ulose O-benzyl-oxime.

ABSTRACT: The title compound, C(19)H(25)NO(6), is a Z diastereomer in which the phenyl ring of the 3-benzyl-oxime substituent and the 5,6-O-isopropyl-idene acetal are both located on the Si-face of the C=N double bond. Inter-molecular C-H?O inter-actions result in helical chains along the b axis of the monoclinic unit cell.

1,2:5,6-Di-O-isopropyl-idene-?-d-3-glucofuranosyl (R(p))-2-(diphenyl-phosphino)ferrocene-1-carboxyl-ate.

Project description:The title compound, [Fe(C(5)H(5))(C(30)H(32)O(7)P)], which is an inter-mediate in the synthesis of (R(p))-2-(diphenyl-phos-phino)ferrocene-1-carboxylic acid, crystallizes in the common chiral space group P2(1)2(1)2(1). In general, the mol-ecular geometry is very similar to that of the corresponding 2,1'-bis-(diphenyl-phosphino) congener. The ferrocene unit assumes a regular geometry with the proximal bulky substituents efficiently avoiding mutual spatial contacts. In the crystal, the mol-ecules participate in weak intra- and inter-molecular C-H?O inter-actions.

1,2:5,6-Di-O-iso-propyl-idene-3-C-methyl-?-d-allo-furan-ose.

Project description:The title carbohydrate, C13H22O6, is a derivative of d-glycose, in which the furan-osidic and iso-propyl-idene rings are in twisted conformations. The mean plane of the furan-osidic ring makes a dihedral angle of 70.32?(18)° with the mean plane of the fused iso-propyl-idene ring. The methyl groups in the other iso-propyl-idene ring are disordered over two sets of sites, with an occupancy ratio of 0.74?(6):0.26?(6). In the crystal, mol-ecules are linked by O-H?O hydrogen bonds into chains with graph-set notation C(5) along [100]. Weak C-H?O interactions also occur.

Project description:The title compound, C21H29NO7 (1) [systematic name: benzyl ({(3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-di-methyl-tetrahydro-furo[2,3-d][1,3]dioxol-6-yl}meth-yl)carbamate], consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring adopts an envelope conformation close to C 3-exo, where the C atom substituted by the benzyl carbamate group is the flap. The fused dioxolane ring also adopts an envelope conformation, as does the terminal dioxolane ring, with in each case an O atom as the flap. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming chains propagating along the b-axis direction.

Project description:The title compound, C(23)H(22)O(8), is a binary benzoyl ester whose nucleus consists of a fused system made up of a methyl-enedi-oxy ring and two tetra-hydro-furan rings.
