A general norbornyl based synthetic approach to carbasugars and 'confused' carbasugars
Mehta, Goverdhan,Talukdar, Pinaki,Mohal, Narinder
, p. 7663 - 7666 (2007/10/03)
The norbornyl system has been recognized simply as a 'locked' carbasugar and a short, general approach to carbasugars and their new siblings, 'confused' carbasugars, from readily available 7-ketonorbornanes is reported.
A norbornyl route to cyclohexitols: Structural diversity in fragmentation through functional group switching. Synthesis of α- and β- galactose, α-talose and α-fucopyranose carbasugars
Mehta, Goverdhan,Mohal, Narinder,Lakshminath, Sripada
, p. 3505 - 3508 (2007/10/03)
A novel fragmentation sequence has been executed within the norbornane system, involving C1-C7 bond scission, to extract a versatile, highly functionalized cyclohexanoid moiety. Its further evolution towards a range-of carbasugars is described. (C) 2000 Elsevier Science Ltd.
SYNTHESES OF PSEUDO-α-D-GLUCOPYRANOSE AND PSEUDO-β-L-IDOPYRANOSE, TWO OPTICALLY ACTIVE PSEUDO-HEXOPYRANOSES, FROM D-GLUCOSE BY USING STEREOSELECTIVE REDUCTIVE DEACETOXYLATION WITH SODIUM BOROHYDRIDE AND CYCLITOL FORMATION FROM NITROFURANOSE AS KEY REACTIO
