Abstract The first highly enantioselective phosphine‐catalyzed formal [4+4] annulation has been developed. In the presence of amino‐acid‐derived phosphines, unprecedented annulations between benzofuran/indole‐derived α,β‐unsaturated imines and allene ketones proceeded smoothly, thus affording azocines, bearing either a benzofuran or an indole moiety, in excellent yields with nearly perfect enantioselectivities (≥98 % ee most cases). This work marks efficient asymmetric construction optically...
The current global transition from conventional fossil-fuel-based systems to green, sustainable, and renewable energy is realizing new challenges associated with device efficiencies. Among the green approaches available, efficient solar conversion into chemical electrical can ensure upcoming demands of future in an environmentally friendly sustainable way. However, sunlight cannot be utilized directly as a result its intermittent diffuse nature. This development economically viable...
Abstract Tungsten oxide/graphene hybrid materials are attractive semiconductors for energy‐related applications. Herein, we report an asymmetric supercapacitor (ASC, HRG//m‐WO 3 ASC), fabricated from monoclinic tungsten oxide (m‐WO ) nanoplates as a negative electrode and highly reduced graphene (HRG) positive material. The performance of the prepared electrodes was evaluated in aqueous electrolyte (1 m H 2 SO 4 using three‐ two‐electrode systems. ASC exhibits maximum specific capacitance...
In this review, we provide an updated account on the recent advances and applications of oxa-Michael reaction in synthesis 5- 6-membered monocyclic oxygen-containing heterocyclic compounds published literature since 2013 to date.
Catalyst-controlled regiodivergent [3 + 2] annulations of aurones and allenoates have been developed.
Abstract A sequential phosphine‐catalyzed asymmetric [3+2] annulation of aldimines with allenoates and oxidative central‐to‐axial chirality transfer strategy has been developed. This approach is operationally simple, allowing for rapid access to a range axially chiral CF 3 ‐containing 2‐arylpyrroles high enantiomeric excess. Furthermore, an atroposelective synthesis esaxerenone presented, illustrating the practical potential reported method.
