A hitherto unreported member of γ-alkylidenebutenolides in Melodorum fruticosum (Annonaceae), (4E)-6-benzoyloxy-7-hydroxy-2,4-heptadiene-4-olide, named as isofruticosinol (4) was isolated from the methanol extract of flowers, along with the known related

In view of biological activities of azole nucleosides and apio-dideoxynucleoside, novel apio nucleoside analogues (1 and 2) with thiazole and triazole base moiety were synthesized using 2,3-O-isopropylidene-apio-β -D-furanose (3), which was prepared from D-mannose.

Reduction of ribono-1,4-lactones and gulono-1,4-lactone as well as ribono-1,5-lactone and glucono-1,5-lactones with LTBH (1.2 equiv.) in CH2Cl2at 0 °C for 30 min provided the corresponding pentose or hexose hemiacetals in high yields. Commonly used in carbohydrate chemistry protecting groups such as trityl, benzyl, silyl, acetals and to some extent acyls are compatible with this reduction.

An array of C-aryl and C-vinyl furanosides were prepared in good yields and diastereoselectivities from C-halogeno furanosides either with aryl Grignard or with vinyl Grignard using the convenient Co(acac)3/TMEDA catalytic system. This method i
Direct C-glycosylation of organotrifluoroborates with glycosyl fluorides and its application to the total synthesis of (+)-varitriol

supporting information; experimental part, p. 42 - 45 (2011/03/22)
A mild, stereoselective, and quick approach to accessing alkynyl and alkenyl C-glycosides via BF3?Et2O promoted coupling of organotrifluoroborates and glycosyl fluorides is reported. The application of this method was further demonstrated by the concise and efficient total synthesis of (+)-varitriol in only seven steps.
One-pot synthesis of acyclic nucleosides from carbohydrate derivatives, by combination of tandem and sequential reactions
Boto, Alicia,Hernandez, Dacil,Hernandez, Rosendo,Alvarez, Eleuterio
, p. 9523 - 9532 (2008/03/28)
(Chemical Equation Presented) The design of processes which combine tandem and sequential reactions allows the transformation of readily available precursors into high-profit products. This strategy is illustrated by the one-pot synthesis of acyclic nucle
