, p. 2859 - 2862 (2019/04/25)
The base-promoted intramolecular cyclization of Ugi-azide adduct has been demonstrated for the synthesis of highly substituted aziridinyl glycoconjugates in one pot. The reactions are scalable and efficient and have an operationally simple broad substrate
Chemoenzymatic synthesis of C8-modified sialic acids and related α2-3- and α2-6-linked sialosides

supporting information; experimental part, p. 5037 - 5040 (2011/10/09)
Naturally occurring 8-O-methylated sialic acids, including 8-O-methyl-N-acetylneuraminic acid and 8-O-methyl-N-glycolylneuraminic acid, along with 8-O-methyl-2-keto-3-deoxy-d-glycero-d-galacto-nonulosonic acid (Kdn8Me) and 8-deoxy-Kdn were synthesized fro
Phosphomolybdic acid supported on silica gel: An efficient, mild and reusable catalyst for the chemoselective hydrolysis of acetonides
Yadav,Raghavendra,Satyanarayana,Balanarsaiah
, p. 2461 - 2464 (2007/10/03)
Carbohydrate acetonides were chemoselectively cleaved to the corresponding diols by using environmentally benign phosphomolybdic acid (H 3PMo12O40) supported on silica gel (PMA-SiO2) at ambient temperature in a
Chemoselective hydrolysis of terminal isopropylidene acetals in acetonitrile using molecular iodine as a mild and efficient catalyst
Yadav,Satyanarayana,Raghavendra,Balanarsaiah
, p. 8745 - 8748 (2007/10/03)
A simple, mild and efficient method for deprotection of acetonides in the presence of molecular iodine is described. Acid labile protecting groups such as PMB, OMe, OBn, allyl and propargyl are compatible with the reaction conditions, while TBS, TBDPS, TMS and THP ethers were unstable under the same conditions.
A mild and efficient method for chemoselective deprotection of acetonides by bismuth(III) trichloride
Swamy, N.Raghavendra,Venkateswarlu
, p. 7549 - 7552 (2007/10/03)
Acetonides undergo chemoselective deprotection to afford the corresponding 1,2-diols in excellent yields using bismuth trichloride in acetonitrile/dichloromethane at ambient temperature.
AN EFFICIENT SYNTHESIS OF (2S,3R)- AND (2S,3S)-SPHINGOSINE
Obayashi, Michio,Schlosser, Manfred
, p. 1715 - 1718 (2007/10/02)
A straightforward sequence of reactions allows the conversion of D(+)-Mannose and D(+)-ribono-1,4-lactone into "erythro"-(2S,3R)- and "threo"-(2S,3S)-sphingosine, respectively.
