  Nonracemic Bicyclic Lactam Lactones via Regio- and cis-Diastereocontrolled C−H Insertion. Asymmetric Synthesis of (8S,8aS)-Octahydroindolizidin-8-ol and (1S,8aS)-Octahydroindolizidin-1-ol

  摘要：

  The Rh-2(MPPIM)(4)-catalyzed intraniolecular C-H insertion reaction of (S)- and (R)-1-benzyl-5-(alpha-diazoacetoxy)piperidin-2-one and (S)-1-benzyl-4-(alpha-diazoacetoxy)pyrrolidin-2-one proceeds with high regioselectivity and cis-diastereoselectivity to give good yields of chiral nonracemic bicyclic lactam lactones (BLLs). For (S)- and (R)-1-benzyl-5-(alpha-diazoacetoxy)piperidin-2-one, the regio selectivity of the C-H insertion is catalyst-dependent; for example, (S)-1-benzyl-5-(alpha-diazoacetoxy)piperidin-2-one undergoes C-H insertion at C-6 preferentially when Rh-2(5S-MPPIM)(4) is used, but with Rh-2(5R-MPPIM)(4), C-H insertion occurs preferentially at C-4. This effect is not observed in the reaction of (S)-1-benzyl-4-(alpha-diazoacetoxy)pyrrolidin-2-one. The utility of the BLLs as chiral building blocks in alkaloid synthesis is exemplified by the synthesis of (8S,8aS)-octahydroindolizidin-8-ol and (1S,8aS)-octahydroindolizidin-1-ol.

  Highly Enantioselective Approach to Indolizidines:  Preparation of (+)-(1S,8aS)-1-Hydroxyindolizidine and (−)-Slaframine

  摘要：

  A highly stereoselective approach to (-)-slaframine and its probable biosynthetic precursor (+)-(1S,8aS)-1-hydroxyindolizidine has been developed based on a diastereofacially selective cycloaddition of dichloroketene with achiral dienol ether.

  (-)-( R)-Pyrrolam A was prepared in five steps, 95% ee and 25% yield, from ( R)-benzyl prolinate. Closure of the pyrrolidine ring was effected by a domino addition-Wittig alkenation reaction with ylide Ph 3 PCCO, immobilized on a polystyrene resin. An indolizidinone was obtained likewise from ( R)-benzyl pipecolate. The reduction of 1-ketopyrrolizidinones and 1-ketoindolizidinones is described.
