A process for the carbonylation of allylic butenyl ether (for example, methyl crotyl ether, 3-methoxybutene-1 and mixtures thereof) or mixture of butadiene and alcohol and production of beta-gamma unsaturated carboxylic acid esters (for example, methyl-3-pentenoate) utilizing a rhodium-containing catalyst for example, dicarbonylacetylacetonate rhodium(I or the like promoted with an iodide-containing compound (for example, HI, AlI3, SnI4, TiI4, CrI3, and CoI2 or the like).
一种将烯丙型丁烯基醚(如甲基巴豆基醚、3－甲氧基丁烯－1及其混合物)或者丁二烯与醇的混合物羰基化的方法，以及由含碘化物化合物(如HI、AlI3、SnI4、TiI4、CrI3和CoI2或等效物)促进，用含铑催化剂如二羰基乙酰丙酮酸铑(I或其等效物制备β－γ不饱和羧酸酯(如甲基－3－戊烯酸酯)的方法。

Firstly, 3-ethylthiobutanal was prepared from crotonaldehyde reacting with ethanehiol in triethylamine with high yield. Secondly, methyl acetoacetate was converted to 6-ethylthiohept-3-en-2-one by three steps via hydrolysis, condensation with 3-ethyltio-butanal and dehydration, then 6-ethylthiohept-3-en-2-one was cycloco ndensed with dimethyl malonate by Michael addition and Claisen condensation, followed by saponification and decarboxylation to give the intermediate of 5-(2-ethylthiopropyl)-cyclohexane-1,3-dione.
首先，以巴豆醛与乙硫醇为原料，在三乙胺的催化作用下高收率制得3-乙硫基丁醛；然后从乙酰乙酸甲酯出发，通过碱水解、与3-乙硫基丁醛缩合、脱水三步反应合成6-乙硫基-3-烯-2-庚酮，接着6-乙硫基-3-烯-2-庚酮与丙二酸二甲酯通过Michael加成和Claisen缩合成环，再通过皂化和脱羧反应生成中间体5-[2-丙基]-1，3-环己二酮；再与丙酸酐反应丙酰化，最后与0-3-氯-2-丙烯基羟胺肟化，得到目标化合物烯草酮。

It is found that the stereochemistry of the reactions of telluronium allylide,crotonylide and trimethylsilyallylide with α,β-unsaturated esters and amides can be tuned by thechoice of reaction conditions.
利用反应条件的变化首次实现了烯丙基、巴豆基、含硅烯丙基碲叶立德与α，β-不饱和酯、酰胺进行环丙烷反应的立体化学调控，能高立体选择性地、高效率地合成两种不同几何异构体中的一个。
