With the rapid development of large-scale complex networks and proliferation various social network applications, amount traffic data generated is increasing tremendously, efficient anomaly detection on those massive crucial to many such as malware detection, load balancing, intrusion detection. Although there are methods around for they all designed single machine, failing deal with case that so large it prohibitive a computer store process data. To solve these problems, we propose parallel...
Aryl boronic acids and esters are important building blocks in API synthesis. The palladium-catalyzed Suzuki-Miyaura borylation is the most common method for their preparation. This paper describes an improvement of current reaction conditions. By using lipophilic bases such as potassium 2-ethyl hexanoate, could be achieved at 35 °C less than 2 h with very low palladium loading (0.5 mol %). A preliminary mechanistic study shows a hitherto unrecognized inhibitory effect by carboxylate anion...
Abstract The access to P-stereogenic motifs has always been considered a very challenging and high attractive mission in modern organic synthesis. While several chiral auxiliaries employed by the practical Jugé-Stephan-like methodology have developed, new type of readily accessible bifunctional ligands toward building still remain much desirable. Herein, we present powerful template, camphor-derived 2,3-diols named CAMDOL, which were designed synthesized from commercially cheap...
Odalasvir is a selective inhibitor of hepatitis C virus NS5A protein, key target for combination therapies. This paper describes the chemical process development synthesis this active pharmaceutical ingredient and improvements that were achieved over medicinal chemistry route. Optimization all reaction conditions crystallizations resulted in higher throughput highly improved mass intensity. The robust has been scaled up to ∼100 kg batches without issues.
Herein, a protocol for copper-catalyzed highly stereo- and regioselective hydrophosphorylation of terminal alkynes to E-alkenylphosphorus compounds was well developed. It represents general practical method, which diarylphosphine oxide, dialkylphosphine oxide dialkyl phosphite all had effective P(O)H parts react with different types alkynes. Contrary previous air-sensitive reports, the reactions proceeded under air. This methodology is quite attractive owing high regioselectivity, good...
Abstract FeCl3‐catalyzed nucleophilic substitution reaction of Baylis–Hillman adducts with alcohols is described. The present protocol allows for the efficient syntheses many kinds functional ethers. This conversion also a green route because water only side product.
Abstract We developed a cascade reaction of o ‐haloaryl ynone and 2‐hydroxy‐2‐methylchromene under transition metal‐free conditions. This strategy proceeds through double Michael addition oxygen‐migration, thus providing straight way for the synthesis chromone derivatives. magnified image
An organobase-catalyzed 1,1-diborylation of terminal alkynes from propargylic derivatives with B 2 oct is first reported, providing 1,1-diborylalkene products high efficiency. The catalytic pathway well postulated on the basis DFT calculations.
A modified Perkow reaction, named Perkow-Shi was developed based on the one-pot α-tosyloxylation of ketones following by addition P(iii)-reagents and 4 Å molecular sieves. Diversity enol phosphates, as well phosphonates, phosphinates, phosphoramidates were synthesized in high yields directly from ubiquitously available instead unfavourable α-chloroketones under a mild environmental friendly condition.
An efficient nucleophilic substitution of Baylis–Hillman adducts with alcohols catalysed by 10 mol% BiCl 3 , affords functionalised ethers. Water was the only side product.
A straightforward and efficient synthesis of functionalized ethers from Baylis-Hillman (MBH) adducts was disclosed. In the presence I2, MBH underwent smooth dehydration to give a series bisallylic symmetrical in moderate good yields.
Currently, the widely used methods for direction of arrival (DOA) estimation were constructed based on subspace, such as Multiple Signal Classification (MUSIC) and Estimating Parameter via Rotational Invariance Techniques (ESPRIT), which required that number sources is known beforehand. In this paper, a new method Vector Error Model (VEM) estimating DOAs was proposed, do not need in advance. The comparison performance between VEM MUSIC model DOA problem given to demonstrate effectiveness our...

Mathematical description of a complex signal is very pivotal but nearly impossible in many engineering cases. The emergency the Generative Adversarial Network (GAN) shows possibility to train network be an Arbitrary Signal Generator (ASG), which only controlled by random vector with several elements. This paper designs ASG model based on 1D GAN, suitable for calculation or curve one dimension. Then, two sets sine wave and triangular are generated program as training samples model. Several...
Mathematical description of a complex signal is very important in engineering but nearly impossible many occasions. The emergence the Generative Adversarial Network (GAN) shows possibility to train single neural network be Specific Signal Generator (SSG), which only controlled by random vector with several elements. However, there no explicit criterion for GAN training process stop, and real applications always stops after certain big iteration. In this paper, serious issue was discussed...
