Total Asymmetric-Synthesis of Polypropionate Fragments and Doubly Branched Heptono-1,4-Lactones

2-Cyano-1,5-dimethyl-7-oxabicyclo[2.2.1]hept-5-en-2-yl (1'R)-camphanate ((+)-3)and (+)-(1R,4R)-1,5-dimethyl-7-oxabicyclo[2.2.1]hept-5-en-2-one ((+)-4) were obtained readily from 3,4-dimethylfuran. (+)-3 was converted into 2,7-dideoxy-2,4-di-C-methyl-L-glycero- and D-glycero-L-altro-heptono-1,4-lactone ((+)-17) and ((+)-18).
