- The amines are organic weak bases which are nitrogen-containing. In the early days of organic chemistry, basic amines derived from natural sources were known as “vegetable alkali”, but they are now referred to as alkaloids. The study of alkaloids provided much of the growth of organic chemistry, phytochemistry and natural products chemistry. It remains a fascinating area of research. Please search for one naturally occurring alkaloid and provide the following: Name of the alkaloid and show its structure. Identify using arrows the polar bonds in the structure Species from where it was isolated What was the use of this alkaloid in plants (if any)? What are the pharmacological, medicinal, or environmental uses or applications of this alkaloid (if any)?arrow_forwardC) a nitrile D) an amine nitrite salt DIRECTIONS: Each of the following questions or incomplete statements below is followed by four suggested answers lettered A - D. Select or choose the letters of the best answer to the question or incomplete statement. 7. An organic nitrogen compound, X, gives ammonia on warming with dilute aqueous sodium hydroxide, X could be A) ethanamide B) ethylamine C) phenylamine D) amino ethanoic acid Which one of the following reagents reacts 1. in a similar fashion with both phenylamine (C H,NH,) and ethylamine. A) Br,(aq) C) conc. HNO, D) cold HNO (aq) 2. Phenylamine (aniline) can be prepared by reducing nitrobenzene with tin and concerntrated hydrochloric acid followed by the addition of alkali and finally steam distillation. The alkali is added to; A) prevent oxidation of phenylamine. B) liberate free phenylamine from solution C) dissolve excess nitro benzene D) dissolve the phenylamine 8.

- b) Compounds in which the –OH of the carboxyl group is replaced by certain other groups are called carboxylic acid derivatives. The most important of which are acyl halides, acid anhydrides, esters and amides. Discuss the relationship between carboxylic acid, acid chloride and acid anhydridearrow_forwardAmines as Bases. Explain ?arrow_forward6. The reaction between aniline and nitrous acid at low temperature yields A) an N-nitroso amine B) a diazonium salt C) a nitrile D) an amine nitrite salt 7.

OH AYA Но B-Estradiol In recent years, chemists have focused on designing and synthesizing molecules that bind to estrogen receptors. One target of this research has been nonsteroidal estrogen antagonists, compounds that interact with estrogen receptors and block the effects of both endogenous and exogenous estrogens. A feature common to one type of nonste- roidal estrogen antagonist is the presence of a 1,2-diphenylethylene with one of the benzene rings bearing a dialkylaminoethoxyl substituent. The first nonsteroidal estrogen antagonist of this type to achieve clinical importance was tamoxifen, now an important drug in the treatment of breast cancer. Tamoxifen has the Z configuration shown here. NMeg A B NMeg ? ОН Tamoxifen Propose reagents for the conversion of A to tamoxifen. Note: The final step in this synthesis gives a mixture of E and Z isomers.arrow_forward2.
