SO DONT B A BALTI AND ANSER ALL MY QUESTIONS NOW.........

For synthesis of Benzopyrrole i.e. Indole the methods of synthesis include Fischers's indole synthesis;  Madelung synthesis,  Reissert synthesis. All these you can get in Organic chemistry vol. I  by  Finar; also you can get it in Pradeep's Organic Chemistry Vol. III by S.N.Dhawan. The reactions are quite lengthy hence could not reproduce them here and also for better understanding if you refer to the original material it will be much helpful. In case of any doubt in the particular step/reaction you may write again.

For oxazole and thiazole also refer to Finar page number 847

2. Are you referring to amyl nitrite as it is related to methyl dopa used in medicine?

3. Chloramphenicol syntheis and structure you can get in Finar Vo. II page no.789-791.

I will try to gather information of the rest of the compounds mentioned in your question. However, I am puzzled why you need all these, is it included in JEE syllabus?
