摘要：

Desaminogirollines syn 2'S,3'S and 2'R,3'R have been prepared from N1-camphosulfonamide 4-carboxaldehyde imidazole and their diastereoisomeric derivatives have been separated. The stereoselective synthesis of chiral natural girolline has been achieved from D(-)arabinose: this ose is condensed with formamidine acetate to obtain a 4(5)-[1',2',3'-trihydroxypropyl]-imidazole; the side-chain is chlorinated before being aminated via an azido compound and the 2-amino group of girolline is obtained by rhodium catalytic reduction of the 2-diazo derivative.
