• The Synthesis of (+)-Preussin and Related Pyrrolidinols by Diastereoselective Paternò-Büchi Reactions of Chiral 2-Substituted 2,3-Dihydropyrroles

  The N-alkoxycarbonyl substituted 2,3-dihydropyrroles 3 and 8 are converted to 2-benzyl-3-pyrrolidinols by the Paterno-Buchi reaction followed by hydrogenolysis. Since the addition of the photoexcited benzaldehyde at the unsaturated heterocycle proceeds in a syn fashion, the benzyl group at C-2 and the hydroxy group at C-3 of the product are cis oriented. The simple and facial diastereoselectivities of the Paterno-Buchi reaction were studied more closely and the relative configuration of the products was elucidated. The thermodynamically less stable endo product is formed as a result of simple diastereoselection. The face differentiation in 2-substituted 2,3-dihydropyrroles is presumably due to the nonplanarity of these heterocycles, which forces attack of the carbonyl group on the face with the existing substituent. All-cis-pyrrolidinols are consequently formed after hydrogenolysis. Following this route, a total synthesis of the pyrrolidinol alkaloid (+)-preussin (1) was conducted, which yielded the target compound in a total yield of 11% over nine steps starting from L-pyroglutaminol (11).

  The total synthesis of (+)-preussin, (2S,3S,5R)-1-methyl-5-nonyl-2-(phenylmethyl)-3-pyrrolidinol, was achieved by using D-glucose as the starting material. The key synthetic steps involved the sequential reduction and cyclization of azido triflate 6 to construct the pyrrolidine moiety 7 with the proper stereochemistry.

  A concise synthesis of (+)-preussin (1), an antifungal agent and a growth-inhibitor of fission yeast and human cancer cells, was accomplished employing a stereoselective aldol reaction between the zinc enolate of 2-undecanone and N-protected-L-phenylalaninal followed by reductive pyrrolidine formation as key steps.
