Synthesis of polyhydroxylated pyrano-pyrrole derivatives from carbohydrate precursors

The efficient synthesis of novel polyhydroxy-tetrahydropyrano-pyrroles from acetylenic carbohydrate precursors in three to four steps is described. The methodology involves, as key steps, the ring contraction of pyridazine intermediates obtained by an inv
