“…Thin layer films of neat diarylethenes were also used to control electrical current. − The electrical conductivity is dependent on both the ionization potential barrier for carrier injection and the mobility of carriers. The ionization potential of the closed-ring isomer is smaller than that of the open-ring isomer.…”

“…In 2009, Kim and co-workers reported the same reaction as Shibasaki but this time catalyzed by Pd(II) complexes using diphosphines as chiral ligands. 25 The room temperature reaction rendered the amine derivatives in moderate to good yields (71-95%) with good diastereo-(up to 100 : 1) and enantioselectivities (70-91%). Following this work the same research group developed the addition of fluorinated ketoesters to N-Boc aldimines catalyzed by chiral Pd(II) catalysts using BINAP (XI) as a ligand.…”

Nucleophilic addition to carbon-nitrogen double bonds (imines) represents one of the most common strategies for the synthesis of amine derivatives. In order to circumvent the problem associated with low reactivity of imines in nucleophilic addition, various imines with electron-withdrawing groups at nitrogen have been studied, and many of them were successfully applied in asymmetric methodologies. Especially N-carbamoyl imines were found to be useful in the enantioselective synthesis of various organic compounds, due to their increased reactivity toward nucleophiles as well as limited difficulties connected with the removal of the carbamoyl moiety in target molecules. The aim of this review is to cover enantioselective methods based on N-carbamoyl imines, focusing on synthetically useful protocols.

“…In addition, the reaction of propargylic alcohols and isocyanates has also been reported . For example, Kang and co‐workers reported a concise one‐step synthesis of 4‐arylidene‐1,3‐oxazolidin‐2‐ones from internal propargylic alcohols and isocyanates using DBU base as catalyst . They also reported the domino cyclization of propargylic alcohols and isocyanates in the presence of N‐heterocyclic carbene catalyst .…”

A general and efficient synthesis of trifluoromethyl-substituted 5-alkylidene-1,3-dioxolanes using AgNO 3 and DBU cooperatively catalyzed domino reaction of propargylic alcohols and trifluoromethyl ketones is described. The reaction tolerates a broad range of functional groups, and the desired products are obtained in good to excellent yields (62-99%) with acceptable diastereoselectivities. a Reaction conditions: 1 (0.3 mmol), 2 (0.36 mmol), AgNO 3 (10 mol%), DBU (10 mol%), toluene (1.0 ml), r.t., 24 h. b Isolated yield. c Determined using 19 F NMR.
