A simple and convenient method for the synthesis of aryl-3,4,6-tri-O-benzyl-2-deoxy-2-methylene-hexopyranosides 5, 6 and 7, glycosides which are not accessible by the conventional Ferrier rearrangement, has been described based on the Mitsunobu reaction o

Synthesis of dihydroxymethyl dihydroxypyrrolidines from C-2 formyl d-glycals has been described via a common dicarbonyl intermediate. The hence obtained pyrrolidines have been further utilized for the synthesis of some steviamine analogues. The newly synthesized molecules have been evaluated for glycosidase inhibition against 6 commercially available enzymes and found to be active in the micromolar range, where one of the steviamine analogues showed good and selective inhibition of β-mannosidase (Helix pomatia).
Synthesis of C-2 methylene glycosides from C-2 propargyloxymethyl glycals exploiting the alkynophilicity of AuCl3

, p. 428 - 432 (2007/10/03)
α and β C-glycosides and oxepane derivatives are prepared by radical reaction opening of glucosyl 1,2-cyclopropane derivatives. Structures have been confirmed by NOE studies of NMR, FABMS and C-H analysis.
Stereoselective synthesis of a ketohexofuranose from an aldohexopyranose by a [6+1-1] strategy

Ozonolysis of 2-acetoxymethyl-1,5-anhydro-3,4,6-tri-O-benzyl-2-deoxy-D- arabino-hex-1-enitol gave 1-O-acetyl-3,4,6-tri-O-benzyl-4-O-formyl-D-arabino- hex-2-ulose (5). Subsequent hydrolysis and acetylation of 5 provided 1,2-di-O-acetyl-3,4,6-tri-O-benzyl-D
The particular sensitivity of silyl ethers of D-glucal toward two Vilsmeier - Haack reagents POCl3·DMF and (CF3SO2)2O·DMF. Their unique and selective conversion to the corresponding C(6)-O-formates
Lellouche,Koeller
, p. 693 - 696 (2007/10/03)
The two electrophilic Vilsmeier - Haack reagents POCl3·DMF 2 or (CF3SO2)2O·DMF 3 mediate the one-step and selective conversion of O-triethylsilyl (O-TES), O-tert-butyldimethylsilyl (O-TBDMS), O-tert-butyldiphenylsilyl (O-TBDPS), and O-triisopropylsilyl (O-TIPS) ethers of D-glucal to the corresponding C(6)-O-formates.

Booma, C.,Balasubramanian, K. K.
, p. 1394 - 1395 (2007/10/02)
Synthesis of tri-O-benzyl-2-C-acetoxymethylglycals and subsequent Ferrier rearrangement to give 2-C-methylene glycosides is described.
