  Evaluation of possible intramolecular [4+2] cycloaddition routes for assembling the central tetracyclic core of the potent marine antiinflammatory agent mangicol A

  摘要：

  A plan for enantioselective construction of the mangicol A framework by means of intramolecular Diels-Alder cycloaddition is outlined. First to be assembled is the enantiopure cyclopentenecarboxylic acid 16. Of the several approaches targeting the 1,3-diene component 56, only that involving palladium-catalyzed enyne cyclization proved successful. Following the coupling of 16 to 56, we were unable to bring about any detectable level of (4 pi+2 pi) cycloaddition. Activation of the diene by incorporation of an OSiEt3 substituent on a terminal sp(2)-hybridized center likewise proved unsuccessful. Further facilitation was sought in the form of cyclopentenonecarboxylate 66. However, thermal activation, Lewis acid catalysis, and high-pressure conditions proved ineffective and did not lead to C-C bond formation. These studies serve to underscore the extent to which steric complications can complicate matters and the extent to which they must be skirted to arrive at the title compound. (c) 2006 Elsevier Ltd.

• Synthesis of optically active cis- and trans-1,2-disubstituted cyclopropane derivatives by the Simmons-Smith reaction of allyl alcohol derivatives derived from (R)-2,3-O-isopropylideneglyceraldehyde

  The Simmons-Smith reactions of Z- and E-allyl alcohol derivatives 6 derived from (R)-2,3-O-isopropylideneglyceraldehyde (5) were used for the synthesis of optically active cis- and trans-1,2 disubstituted cyclopropane derivatives. Reaction of 6 with diethyl zinc and diiodomethane gave cyclopropane derivatives 7 in 84% to quantitative yields with 35 to approximate to 100% des. Identical facial selectivities toward the double bonds, Ire-asi for Z-6 and 1re-2re for E-6, were observed in the cyclopropanations. The diastereoselectivity was dependent on the protecting group on the terminal allylic oxygen (R of 6, TBDPS > MOM > Bn) and on the stereochemistry of the double bond (Z > E). For TBDPS ethers Z- and E-6c, cis- and trans-7c were obtained as single diastereomers respectively. It was clearly demonstrated that the stereoselectivity of the cyclopropanation is controlled by the directing effect of the allylic oxygen (O-1) of the dioxolane ring which coordinates to the reagent. The terminal allylic oxygen (O-2) lowered the diastereoselectivity This reaction was applied to the synthesis of optically active cyclopropane analogs of gamma-aminobutyric acid (GABA) 18, 22, and ent-22.
