  Regiochemical control of the ring-opening of 1,2-epoxides by means of chelating processes. 2. Synthesis and reactions of the cis- and trans-oxides of 4-[(benzyloxy)methyl]cyclohexene, 3-cyclohexenemethanol, and methyl 3-cyclohexenecarboxylate

  摘要：

  The synthesis of the diastereoisomeric epoxides cis-1b-d and trans-2b-d and the products of their ring-opening by various nucleophiles are described. The results of the ring-openings of the trans-epoxides 2b-d can be rationalized by combining stereoelectronic and conformational arguments. However, the regioselectivity of the ring-openings of the cis-epoxides 1b-d can, in principle, be influenced by the chelation of a metal ion by the oxygen atom of the epoxy group and that of the substituent on the 4-position. The results of the reactions of the cis-epoxides 1b-d indicate that, to some degree, chelation is indeed a factor. How important a factor it is is dependent both on the reaction conditions and on the concentration and nature of the metal ion. In the ring-openings of the cis-epoxides 1b and 1d, chelation seems to be a larger factor than it is in the ring-openings of cis-epoxide 1c. However, in no case is chelation as large a factor as it was in the ring-openings of the cis-epoxide 1a, which was studied earlier. On the other hand, the autocatalyzed methanolysis, under neutral conditions, of epoxy acid 1e, followed by CH2N2 methylation of the crude product, afforded a mixture of the two regioisomeric hydroxy ethers in which the C-2-type compound predominates. This result suggests that intramolecular hydrogen bonding may determine the reactive conformation of 1e.

  The present invention relates to production of polyketides and other natural products and to libraries of compounds and individual novel compounds. One important area is the isolation and potential use of novel FKBP-ligand analogues and host cells that produce these compounds. The invention is particularly concerned with methods for the efficient transformation of strains that produce FKBP analogues and recombinant cells in which cloned genes or gene cassettes are expressed to generate novel compounds such as polyketide (especially rapamycin) FKBP-ligand analogues, and to processes for their preparation, and to means employed therein (e.g. nucleic acids, vectors, gene cassettes and genetically modified strains).
