In a further aspect, the disclosure relates to the products of the disclosed methods, i.e., terpene and terpene-like molecules prepared using the disclosed methods. Intermediates for the synthesis of a wide variety of terpenoids are γ-allyl Knoevenagel adducts or quasi γ-allyl Knoevenagel adducts are disclosed. In various aspects, methods of preparing terpenoids through these intermediates are disclosed. The methods can comprise α-alkylation of an allylic electrophile followed by ring-closure metathesis to a polycyclic terpenoid structure. In a further aspect, the disclosure pertains to terpenoid frameworks, and compounds prepared via disclosed oxidation and substitution reactions on the disclosed terpenoid frameworks. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

专利号:US-4547323-A 优先权日:1984-03-21 标 题 :Synthesis of 2,2-dimethyl-4-methyleneglutaric acid and derivatives 发明人:CARLSON GARY M 权利人:SCM CORP 摘要:The process comprises dimerizing methacrylic acid derivatives in the presence of an organic Co(II) glyoxime to produce 2,2-dimethyl-4-methyleneglutaric acid and/or derivatives thereof. Methacrylic acid derivatives include methacrylic acid or derivatives of methacrylic acid. The composition produced by the process comprises a glutaric dimer acid which can be further polymerized to form high molecular weight polymer useful as a binder in protective coatings.
专利号:US-7763734-B2 优先权日:2006-04-19 标题 :Synthesis, structure and use of bisoxazolidines for asymmetric catalysis and synthesis 发明人:WOLF CHRISTIAN; LIU SHUANGLONG 权利人:UNIV GEORGETOWN 摘要:One aspect of the invention relates to chiral bisoxazolidines and their use in asymmetric catalysis. The chiral bisoxazolidines are a novel class of compounds that is expected to find multiple applications, for example, in asymmetric synthesis. For example, a bisoxazolidine ligand enabled the catalytic enantioselective alkynylation and alkylation of a range of aromatic and aliphatic aldehydes, generating chiral propargylic alcohols and secondary alcohols in high yields and enantiomeric excess.
专利号:EP-0723402-B1 优先权日:1993-08-30 标 题 :Senescent cell-derived inhibitors of dna synthesis 发明人:SMITH JAMES R 权利人:BAYLOR COLLEGE MEDICINE 摘要:An expression vector cDNA library derived from senescent cells has been used to isolate cDNA clones that encode inhibitors of DNA synthesis. Such inhibitors play a role in cellular senescence, aging and neoplasia. Antisense nucleic acids reduce the inhibition of DNA synthesis. The invention concerns such molecules, their inhibitors, antagonists and derivatives. The invention also concerns diagnostic, therapeutic and in vitro uses for all such agents.
