“…Chemistry has been a part of human life and civilization (Harari, 2017). The greatest benefits of chemistry can be felt by society and become an integral part of modern human life (Lancaster, 2002;Patil et al, 2011). However, the perception of chemistry today faces the dynamics of thinking, namely the demand for more advanced products produced by this field, and on the other hand faces bad perceptions in the form of fear and suspicion in the community (Clark & Macquarrie, 2007).…”

This is very important in growing students' environmental awareness through integrating green chemistry in learning as one of the efforts to protect the environment and reduce environmental pollution. Chemistry learning through green chemistry education has great potential in developing ethics as a method for solving environmental problems. Green chemistry has 12 principles that are expected to address pressing environmental problems such as pollution, waste management, energy shortages, and workplace safety and security. This research type is descriptive. As much as 77% of the average students in this study with a good enough category indicates that green chemistry has an important role in building chemistry ethics. Ethics is used in general to describe human attitudes towards a problem. Ethics education in chemistry with a green chemistry perspective is carried out by teaching and training integrated into courses with the hope that it will become ethical habituation that will build chemistry ethics.

“…The classical Biginelli reaction requires long reaction times (20 hrs), use of sulphuric acid and often suffers from low yields of products in case of substituted aromatic and aliphatic aldehydes. Multi-step synthesis produces somewhat higher yields but lacks the simplicity of original one-pot Biginelli protocol [14] Figure 3. Therefore, the Biginelli reaction continues to attract the attention of organic chemists interested in finding milder and more efficient procedures for the synthesis of dihydropyrimidinones [15].The feasibility of performing multi-component reactions under solvent-free conditions could enhance their efficiency from an economic as well as ecological point of view.…”

A simple and precise green synthesis method that have been used to synthesis of dihydrtopyrimidinone (DHPMs) and their sulphur analogue dihydropyrimidinthione derivatives traditionally to carry out the conventional Biginelli reaction involves three-component one-pot condensation of an aldehyde, β-ketoester and urea or thiourea in ethanol under strong acidic condensation HCl. The dihydropyrimidinone (DHPMs) and their sulphur analogue dihydropyrimidinthione derivatives which are act as antibacterial, anti-inflammatory, antimalarial agents, and antiviral, antitumor, hypnotic's etc. by green chemistry approach. These reactions were performed by three-component condensation of different types of an aldehyde (benzaldehyde, acetaldehyde, furfural, cinnamaldehyde, and salicaldehyde), ethyl acetoacetate, and urea or thiourea at reflux temperature under solvent-free conditions without catalyst to afford the corresponding dihydropyrimidinones and dihydropyrimidinthione in excellent yields (80-95%). The advantages of this green chemistry approach the excellent yield, short time, operational simplicity, and the avoidance of the use of organic solvents and friendly preparation. Products obtained were identified using physical and spectroscopic IR, 1 HNMR, GC. Mass, UV, techniques.
