Synthesis of 6-amino-6-deoxy-d-gulono-1,6-lactam and l-gulono-1,6-lactam derived from corresponding 5,6-O-sulfinyl hexono-1,4-lactones
摘要:
Syntheses of 6-amino-6-deoxy-2,3-0-isopropylidene-D-gulono- and L-gulono-1,6-lactams 3 and 4 from corresponding glycono-1,4-lactones are described. Activation of the primary hydroxyl group requires 5,6-cyclic sulfite intermediate to obtain 6-azido-6-deoxy derivatives, which are cyclized after reduction. (c) 2006 Elsevier Ltd.
