  A versatile method for the hydrolysis of gem-dibromomethylarenes bearing carboxylate or boronate group into aldehydes

  摘要：

  Hydrolysis of geni-dibromomethylarenes bearing carboxylate or boronate group to corresponding aldehydes without affecting the ester group was successfully accomplished in high yields by subjecting them to refluxing pyridine. Both aromatic and heteroaromatic substrates gave the corresponding aldehydes in good yields. This method was efficiently adapted for the large scale synthesis of 2d and 2f. (C) 2007 Elsevier Ltd.

  the preparation of α,β-unsaturated carboxylic acids and corresponding esters with (E)-stereoselectivity via the TiCl4-mediated olefination of aldehydes. The method, which uses readily available acetic acid or its alkyl esters as active methylene partners, is more flexible and complementary to conventional routes in the preparation of (E)-cinnamic acid derivatives.

  已经开发了一种新的方法，用于通过TiCl 4介导的醛的烯化反应制备具有（E）-立体选择性的α，β-不饱和羧酸和相应的酯。该方法使用现成的乙酸或其烷基酯作为活性亚甲基伴侣，在制备（E）-肉桂酸衍生物时，它比常规方法更具灵活性和互补性。
• Total synthesis of (+)-Z-deoxypukalide, a furanobutenolide-based cembranoid isolated from the pacific octocoral Leptogorgia spp.

  A total synthesis of (+)-Z-deoxypukalide 3 using a combination of Stille and Nozaki-Hiyama-Kishi(NHK) coupling reactions as key steps, is described. During this study a new practical synthesis of the substituted butenolide intermediate 10, based on a combination of RCM and CM reactions from the cyclobutene ester 21 in the presence of 2-methylpropenol was also developed. Attempts to apply the intramolecular NHK reaction to the substrates 8a and 8b containing an ester group adjacent to the reacting aldehyde functionality gave disappointing low yields (<6%) of the corresponding coupled products 9. The synthetic (+)-Z-deoxypukalide 3 was correlated with naturally derived material, and also with pukalide 1, the first member of the furanobutenolide-based cembranoids to be isolated from corals.
