  Lasonolide A:  Structural Revision and Total Synthesis

  摘要：

  The proposed structure of lasonolide A was synthesized employing radical cyclization reactions of beta-alkoxyacrylates for preparation of the tetrahydropyranyl units A and B, but the spectroscopic data did not match those of the natural product. Both enantiomers of a revised structure featuring 17E,25Z double bonds were synthesized, and the (-)-isomer was found to be the biologically active enantiomer.

  Synthesis and evaluation of lasonolide A analogues

  摘要：

  Homolasonolide A and 10-desmethyllasonolide A are biologically less active than lasonolide A. The ethyl ester analogue of lasonolide A exhibited higher activity than the parent compound in some biological test. (C) 2004 Elsevier Ltd. All rights reserved.

• Divergent reaction pathways in amine additions to β-lactone electrophiles. An application to β-peptide synthesis

  β-Lactone electrophiles are subject to regioselective addition–elimination (AE) or SN2 ring opening with various nitrogen-based nucleophiles. Primary and secondary amines promote AE ring opening to deliver products that are the functional equivalent of amide aldol adducts. Azide and sulfonamide anion nucleophiles engender SN2 lactone ring opening to deliver N-protected β-amino acid derivatives. These

  Hydrogenation of enantioenriched β-hydroxy ketones promoted by the catalyst generated in situ from commercially available and inexpensive RuCl3 and PPh3 under hydrogen pressure allowed the efficient preparation of a variety of anti-1,3-diols in good yields and with a high level of diastereoselectivity. This method should be an interesting alternative to organoboron reagents for the diastereoselective
