In this research, six samples of valid and widely soil-water retention curve (SWRC) estimation models, including van Genuchten, Brooks Corey, Fredlund Xing, Durner, Kosugi, Seki were studied. To realize approach, in the first step, accuracy each model was calculated using ten statistical benchmarks, then numbers obtained from fitting standardized based on benchmark by standard fuzzy method so t...

This work describes catalytic and asymmetric aziridinations (15 examples, 95-98% ee) of benzyl bromide and imines via the imino Corey-Chaykovsky reaction using (thiolan-2-yl)diarylmethanol benzyl ether as an organocatalyst. The catalyst and analogues thereof were prepared through an expeditious and efficient synthetic route featuring a double nucleophilic substitution and Shi epoxidation as key...

A straightforward, efficient, and reliable approach to synthetically valuable 2,3-dihydrofurans via a reaction between Corey ylide and α,β-unsaturated ketones has been developed. The use of simple and widely spread starting materials as well as mild reaction conditions and scalability provide a broad scope of 2,3-dihydrofurans.

A general and direct strategy for the synthesis of chiral spiro-aziridine oxindoles has been developed via an aza-Corey-Chaykovsky reaction of isatin-derived N-tert-butanesulfinyl ketimines with excellent selectivity (dr = 98:2 to >99:1). The method is explored for the synthesis of chiral 3-substituted spiro-aziridine oxindoles with high (2S,3S)-selectivity over (2S,3R).
