โฆ Synopsis
There are four theoreti~lly possible stereoisomers of 2,3-diamino-l-cyclohexanols, each of which is dissymmetric and therefore racemic. The (1,2/3)-l and the (1,3/2)-stereoisome? are known, and syntheses of the (l/2,3)-( 6) and the (1,2,3/0)stereoisomer ( 13) are now reported.
Starting from known (1 ,3~2)-2-amino-1,3-cyclohexanedio13 (l), (l/2,3)-2,3-dia-* Dedicated to Professor Leslie Hough in the year of his 65th birthday. Aminocyclitols, Part 37.
