The conversion of α‐diazo ketones into ketenes, and products derived therefrom, was
discovered by Wolff in 1902. Major applications of the Wolff rearrangement, such as the …

The recent discovery of several potent antiturnor antibiotics containing (Z)-enediynes or
rented systems has pushed the exploration of enediynes to the forefront of chemical and …

Metal carbene, as a reactive intermediate, has shown versatile applications in modern
organic synthesis. One of the priorities in this area is exploration of stable carbene …

A wide variety of substituted naphthalenes are readily prepared regioselectively under mild
reaction conditions by the 6-endo-dig electrophilic cyclization of appropriate arene …

An easy synthesis of (Z)-1-alkylidene-1, 3-dihydroisobenzofurans and 1H-isochromenes by
palladium-catalyzed cycloisomerization of readily available 2-alkynylbenzyl alcohols under …

A series of 4-Se-(Te, S)-isochromenones and 3-substituted isochromenones were
synthesized in good yields via FeCl3-mediated cyclization of alkynylaryl esters with different …

The rhodium (II)-catalyzed reaction of α-diazo ketones bearing tethered alkyne units
represents a new and useful method for the construction of a variety of substituted …

In an effort to lower the temperatures required to prepare multicyclic compounds using the
tandem enediyne− radical cyclization, we have developed the tandem enyne allene− radical …

An iron‐promoted electrophilic annulation of aryl enynes with disulfides or diselenides has
been developed. In the presence of iron (III) chloride (FeCl3) and iodine (I2,), a variety of …

An efficient synthetic method of functionalized naphthalenes having hydrogen, alkyl, alkenyl,
aryl, or heteroaryl groups on the 4-position and ethoxycarbonyl group on the 2-position was …
