you're thinking too far.

First, create a symlink like this:
/home/jjobanputra/code/coupon/coupons => /home/jjobanputra/code/coupon/upload

(eg.
ln -s /home/jjobanputra/code/coupon/upload /home/jjobanputra/code/coupon/coupons
)

Using alias is a shortcut for getting headache.

then the config:

#order is important.
location ~ ^/coupons/.*\.php$ {
  root /home/jjobanputra/code/coupon;
  try_files $uri =404;
  fastcgi_pass 127.0.0.1:53217;
  fastcgi_index index.php;
  #probably not needed - it should be covered in fastcgi.conf
  fastcgi_param SCRIPT_FILENAME $request_filename;
  include /opt/nginx/conf/fastcgi.conf;
}

location /coupons/ {
  root /home/jjobanputra/code/coupon;
  index index.php index.html index.htm;
  #this line below probably not going to work as expected
  #the alternative is to capture the url using location ~ ^/coupons/(.*)
  # and use it as parameter replacing uri in q=$uri
  #another possible hack is using @location and rewrite.
  try_files $uri $uri/ /coupons/index.php?q=$uri;
  expires 30d;
}

#I find this mandatory for any kind of rewrites.
#Especially if the root is different than the global root.
#Basically a behaviour difference.
location = /coupons {
  rewrite ^ /coupons/ permanent;
}
