Hashimura, Kazuya published the artcileA stereocontrolled route to both enantiomers of the necine base dihydroxyheliotridane via intramolecular 1,3-dipolar addition using the same chiral precursor, Related Products of chlorides-buliding-blocks, the publication is Journal of the Chemical Society, Chemical Communications (1995), 2291-2, database is CAplus.
Diastereofacial selectivity in an enantiospecific intramol. 1,3-dipolar addition is controlled by adjusting the size of the tether between the dipole and the dipolarophile to give 2,3-disubstituted pyrrolidines enantiomeric with respect to the newly generated stereogenic 2,3-centers depending on the tether size; this leads to stereocontrolled synthesis of the (-)-(I) and (+)-enantiomers of the necine base dihydroxyheliotridane from chiral O-benzylglycidol.
