Synthesis of dihydroxylated prolines and iminocyclitols from five-membered endocyclic enecarbamates. Total synthesis of the potent glycosidase inhibitor (2R,3R,4R,5R)-2,5-dihydroxymethyl-3,4-dihydroxypyrrolidine (DMDP)

cis- and trans-3,4-Dihydroxylated prolines and the iminocyclitol 1,4-dideoxy-1,4-imino ribitol were synthesized employing a strategy involving the Heck arylation of five-membered endocyclic enecarbamates with aryldiazonium salts followed by oxidative cleavage of the electron-rich aromatic ring. The total synthesis of the potent α- and β-glucosidase inhibitor (2R,3R,4R,5R)-2,5-hydroxymethyl-3,4-dihydroxypyrrolidine (DMDP) was also achieved by the same strategy in ten steps from a chiral five-membered enecarbamate in 12% overall yield.

Total enantioselective synthesis of the natural (-)-codonopsinine was accomplished in seven steps with an overall yield of approximately 16% starting from the five-membered endocyclic enecarbamate 4. The total synthesis features a highly efficient and ste
Heck reaction of endocyclic enecarbemates with diazonium salts. Formal enantioselective syntheses of alkaloids (-)-codonopsine and (-)- codonopsinine, and the synthesis of a new C-aryl azasugar

Formal total syntheses of the pyrrolidine alkaloids (-)-codonopsine and (-)-codonopsinine, as well as the synthesis of a new C-aryl azasugar were accomplished from a common 5-membered, enantiomerically pure endocyclic enecarbamate. The key step in those s
