• ]. A final hydrogenation step gave aminopyran 30 in high overall yield. Aminopyrans 24, 26, 28 and 30 can be regarded as mimetics of differently configured (2-deoxy) 4-amino sugars [24][25][26]. Aminopyrans 24 and 28 have already been linked via amide bonds to the thiol shell of gold nanoparticles
