Synthesis of isofagomine and some new azasugars as glycosidase inhibitors from d-mannitol derived nitroolefins
Roy, Rashmi,Kancharla, Pavan K.,Reddy, Y. Suman,Brar, Anita,Vankar
, p. 1502 - 1513 (2013)
The synthesis of isofagomine, epi-isofagomine and isofagomine analogues along with some new azasugars from two different vinyl nitro compounds, that were derived from d-mannitol, has been carried out. Two different synthetic strategies were followed for e
Asymmetrized tris(hydroxymethyl)methane as precursor of iminosugars: Application to the synthesis of isofagomine
Guanti, Giuseppe,Riva, Renata
, p. 357 - 360 (2003)
A new synthetic application of asymmetrized tris(hydroxymethyl)methane (THYM*), readily obtained in both enantiomeric forms through a chemoenzymatic procedure, is reported. In this case THYM* precursor 3 was elaborated by ring closing metathesis into some enantiopure branched tetrahydropyridines, that have been used as precursors of the potent glycosidase inhibitor isofagomine 28.

, p. 633 - 645 (2007)
The asymmetric synthesis of all stereoisomers of isofagomine from 5-hydroxymethyl-3-piperidene 6, which was prepared by [2,3 ]-Wittig rearrangement of O-alkylstannylmethyl compound 5 derived from readily available chiral 3-hydroxypiperidene 4, is describe

Aza-Claisen rearrangement of 2-C-hydroxymethyl glycals as a versatile strategy towards synthesis of isofagomine and related biologically important azasugars
Reddy, Y. Suman,Kancharla, Pavan K.,Roy, Rashmi,Vankar, Yashwant D.
, p. 2760 - 2773 (2012/11/07)
Synthesis of isofagomine has been achieved by implementation of aza-Claisen rearrangement of 2-C-hydroxymethyl glycals as a key step. The above rearrangement has also been utilized in the synthesis of biologically important polyhydroxylated piperidine frameworks such as isogalactofagomine, ent-isogalactofagomine and their analogues and some other azasugars as glycosidase inhibitors.

Asymmetric synthesis of polyhydroxylated N -alkoxypiperidines by ring-closing double reductive amination: Facile preparation of isofagomine and analogues
Malik, Gaelle,Guinchard, Xavier,Crich, David
, p. 596 - 599 (2012/02/16)
A de novo synthesis of novel polyhydroxylated N-alkoxypiperidines based on the ring-closing double reductive amination of 1,5-dialdehydes, obtained by oxidative cleavage of cyclopentene derivatives, with O-substituted hydroxylamines is reported. Isofagomine was accessed by cleavage of the N-O bond of an N-alkoxypiperidine.
Acceleration effect of an allylic hydroxy group on ring-closing enyne metathesis of terminal alkynes: Scope, application, and mechanistic insights
Imahori, Tatsushi,Ojima, Hidetomo,Yoshimura, Yuichi,Takahata, Hiroki
experimental part, p. 10762 - 10771 (2009/12/01)
An interesting acceleration effect of an allylic hydroxy group on ring-closing enyne metathesis has been found. Ring-closing enyne metathesis of terminal alkynes possessing an allylic hydroxy group proceeded smoothly without the ethylene atmosphere generally necessary to promote the reaction. The synthesis of (+)-isofagomine with the aid of this efficient reaction has been demonstrated. Mechanistic studies of the acceleration effect were also carried out. Results of NMR studies suggested that the reaction proceeded via an "ene-then-yne" pathway. Kinetic studies indicated switching of the rate-determining step as a consequence of the presence of an allylic hydroxy group. These results suggest acceleration of the reentry step of Ru-carbene species by the allylic hydroxy group.
