Abstract

1-Amino-1-deoxy-D-glucitol (3) was converted into the 3, 4; 5, 6-di-O-isopropylidene protected ammonium salt 17 which was transformed further into the trans-fused piperidine acetonides 4–8 in six steps and 23–32% overall yield. In the final step, ring closure was effected via cleavage of the N-Boc group of intermediates 27–29 with trimethylsilyl iodide: this enabled internal, face selective 1, 4-addition of the free amino group to the (5, 6)-α, β- ...
