A new annulation reaction leading to tetrahydropyrans has been discovered. The reaction of homoallylic enol ethers (e.g., 1) with alpha,beta-unsaturated ketones or esters begins with a Mukaiyama-Michael addition. The intermediate oxocarbenium ion undergoes a rapid 2-oxonia-Cope rearrangement, and the resulting zwitterion collapses to form a tetrahydropyran. The reaction is stereoselective with 3-butene-2-one

functionalized 1,3‐diol derivatives is reported. Employing a copper‐catalyzed oxy‐alkenylation strategy, a range of readily available, substituted homoallylic alcohol derivatives and alkenyl(aryl) iodonium salts combine to form syn‐1,3‐carbonates in excellent yield and with high selectivity. Furthermore, the products formed are amenable to an iterative reaction sequence, thus affording highly complex polyketide‐like

InI 3 -catalyzed hydroallylation of esters by using hydro-and allysilanes under mild conditions has been accomplished. Many significant groups such as alkenyl, alkynyl, cyano, and nitro ones survive under these conditions. This reaction system provided routes to both homoallylic alcohols and ethers, in which either elimination of the alkoxy moiety or of the carbonyl oxygen atom could be freely selected
通过在温和条件下使用氢化硅烷和烯丙基硅烷完成了 InI 3 催化的酯的氢化烯丙基化。许多重要的基团,如链烯基、炔基、氰基和硝基基团在这些条件下仍然存在。该反应体系为高烯丙醇和醚提供了途径,其中烷氧基部分或羰基氧原子的消除可以通过改变烷氧基部分和氢硅烷上的取代基自由选择。此外,内酯的氢烯丙基化发生在不开环的情况下,以高产率生产所需的环醚。
