Transition-metal-catalyzed reaction of diazocompounds, efficient synthesis of functionalized ethers by carbene insertion into the hydroxylic bond of alcohols
An Efficient catalytic synthesis of unsaturated ethers by carbeneinsertion (with diazoesters as carbene precursors) into the OH bond of unsaturated alcohols is reported. The regioselectivity for the OH insertion is high. However, depending on the catalyst counter-ions and the diazoester alkoxy group, addition to the unsaturated centre can be promoted to some extent, yielding then cyclopropyl and cyclopropenyl
The first asymmetric nickel‐catalyzed intramolecular reductivecyclization of alkynones is reported. A P‐chiral monophosphine and triethylsilane were used as the ligand and the reducing reagent, respectively, to form a series of tertiary allylic alcohols bearing furan/pyran rings in excellent yields and enantioselectivities. This reaction has a broad substrate scope and enabled the efficient synthesis
The Photo-Dehydro-Diels–Alder (PDDA) reaction is shown to be a versatile method for the preparation of highly functionalized naphthalenes. Thus, ketones 1 could be cyclized to the 1H-benzo[g]isochromen-4-(3H)-ones 11 and 12, mostly in good yields. The influence of various substituents on the regioselectivity of the reaction was investigated, and the mechanism is discussed based on theoretical calculations
事实证明,光脱氢-狄尔斯-阿尔德(PDDA)反应是制备高官能度萘的通用方法。因此,酮1可以环化成1 H-苯并[ g ]异色n-4-(3 H)-酮11和12,大部分收率很高。研究了各种取代基对反应区域选择性的影响,并在理论计算的基础上探讨了机理。
