This study aims to investigate the effect of good corporate governance (GCG) on sustainability performance (CSP) using Triple Bottom Line (TBL) approach in a two-tier GCG system. is measured by size and education background board commissioners (BoC) top management team (TMT). CSP consists economic, social, environment performance. As many as 117 sample data were collected from financial stateme...

Enantiopure 2-(tributylstannyl)pyrrolidine hydroiodide may be prepared in excellent yield by TMSI treatment of the corresponding N-Boc compound, which is in turn prepared by asymmetric deprotonation (s-BuLi.sparteine) and stannylation, as described in the literature. Crystals of the hydroiodide salt suitable for X-ray analysis were obtained, and although there is some disorder about the butyl g...

This study seeks to empirically evaluate the influence of Return on Assets (ROA) and Net Profit Margin (NPM) stock prices that are moderated by size board commissioners (BoC). An archival using Moderated Regression Analysis (MRA) technique was conducted consumer goods businesses listed Indonesia Stock Exchange (IDX) for years 2015 through 2019. The purposive sampling method used compile a sampl...

Tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and N-Boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (MTSA). All reactions were performed at room temperature in good to high yields.

The Diophantine equation has been studied by many researchers in number theory because it helps solving variety of complicated puzzle problems. From several studies, interesting proofs have found. In this paper, the researcher examined solutions (

Isocyanide-based multicomponent reactions (IMCR) are by far the most versatile reactions that can construct relatively complex molecules by one-pot synthesis. More importantly, the development of post IMCR modifications significantly improves the scaffold's diversity. Here, we describe the use of N-Boc protected hydrazine together with α-amino acid derived isocyanides in the Ugi tetrazole react...

Amine precursors such as NH-Boc (5) and NH-formyl (6) protected glycines were grafted by esterification on the hy-droxylated arms of 1-(2-hydroxyethyl)-3-methylimidazolium hexafluorophosphates 4h or tetrafluoroborates 4t. The Boc cleav-age was then realized at room temperature by successively treating acetonitrile solutions of the carbamates 7h or 7t with methanol and acetyl chloride (2 equival...

A hybrid granularity model is proposed for general concurrent solution. It is applied to the triangular factorization of a dense matrix ranging in size from 4 to 1024. Concurrency is achieved at two levels: (!) with small (micro) task granularity and (2) with large (blocked) task granularity. Rdevano~ to a many-proccssax CRAY X-MP is demonstrated by simulation.

A new chiral serine equivalent and its enantiomer have been synthesized from (S)- and (R)-N-Boc-serine methyl esters (Boc: tert-butyloxycarbonyl). The use of these compounds as chiral building blocks has been demonstrated in the synthesis of alpha-alkyl alpha-amino acids by diastereoselective potassium enolate alkylation reactions and subsequent acid hydrolyses. Theoretical studies were perform...
