  摘要：

  The dilithiation of beta-tosylated propanoic, 2-methylpropanoic, and butanoic acid 10 with n-butyllithium at -78 degrees C leads to the corresponding lithium 3-lithio-3-tosylalkanoates 11. They react with different electrophilic reagents (deuterium oxide, iodine, trimethylchlorosilane, alkyl halides, and acyl chlorides) to give the corresponding 3-substituted tosylated alkanoic acids 12. When carbonyl compounds are allowed to react with intermediates 11 followed by in situ lactonization with trifluoracetic anhydride and base-promoted elimination alpha,beta-butenolides are obtained. This methodology is applied to the direct synthesis of the rosefuran lactone precursor 14cg, the O-benzyl derivative of (+/-)-umbelactone (14ch), and (+/-)-andirolactone (14ci). The alkylation and acylation reactions of organolithium compounds 11 followed by esterification with hydrogen chloride in methanol and treatment with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) afford alpha,beta- and/or beta,gamma-unsaturated esters 17 and/or 18 and unsaturated 4-keto esters 19, respectively. The last methodology has been applied to the synthesis of the unsaturated 4-keto ester 19ae precursor of the seco acid of (+/-)-pyrenophorin (22).

  Photolysis of chromium alkoxycarbene complexes in the presence of stabilized ylides produced allenes having effect withdrawing groups on C-1 and electron donating groups on C-3. These highly reactive captodative allenes rearranged to 1,3-substituted-1,3-dienes under mildly acidic conditions and hydrolyzed to γ-ket-α,β-unsaturated esters, both in excellent yield
