A rhodium complex coordinated with a trans-chelating chiral diphosphine (S,S)-(R,R)-PhTRAP was an effective catalyst for asymmetric hydrogenation of N-acyl-1-aza-2-cycloalkene-2-carboxylates, which gave the corresponding protected cyclic α-amino acids wit

(-)-Cryptopleurine 1 is one of the most potent anti-proliferative member of the phenanthroquinolizidine class of alkaloids. We report here the synthesis of (-)-6-O-desmethylcryptopleurine (-)-2 and (-)-6-O-desmethyl-(15R)-hydroxycryptopleurine (-)-4 in th

The organocatalytic one-pot oxidative cleavage of terminal 1,2-diols to one-carbon-unit-shorter carboxylic acids is described. The combination of 1-Me-AZADO (cat.), NaOCl (cat.), and NaClO2 caused smooth one-pot oxidative cleavage under mild conditions. A broad range of substrates including carbohydrates and N-protected amino diols were converted without epimerization. Terminal triols and tetraols respectively underwent cleavage of their C-2 and C-3 moieties to afford their corresponding two- and three-carbon-unit-shorter carboxylic acids.
