Simultaneous construction of C-C, C-O, and C-N bonds utilizing Cs2CO3 as a source of carbonyl (CO) and ethereal oxygen and a cascade synthesis of benzofuro[3,2-c]quinolin-6(5H)-one are achieved using a combination of Cu(OAc)2 and Ag2CO3.

The simultaneous construction of C–C, C–O, and C–N bonds utilizing Cs2CO3 as a source of both carbonyl (CO) and ethereal oxygen and a cascade synthesis of benzofuro[3,2-c]quinolin-6(5H)-one have been achieved using a combination of Cu(OAc)2 and Ag2CO3. A plausible mechanism has been proposed for this unprecedented transformation.

NIGERIAN FOOD
Are you planning a trip to Nigeria? One fun idea or activity you have to include in your itinerary without a doubt is to try out the food. As a multi-ethnic country, Nigeria is a fertile ground for ridiculously delicious delicacies. From the east, west, north and south to virtually every in-between corners of the country, our plethora of spice-rich flavourful dishes are what ties us together. To make it easy for you, here’s a selection of 20 popular Nigerian food to get you started on this journey of tastes.

1. Pounded Yam

Yam, which is widely available is boiled and pounded into a smooth mash. You’ll most likely find people eating pounded yam with Egusi, Banga, Ogbono or some other meal.
Mind you, Nigerians abroad prepare alternative pounded yam using yam flour, but it doesn’t taste like the original pounded yam. Although, the Yoruba people are known to be fond of pounded yam, some other Nigerian tribes like the Ibos consume it especially during occasions such as during the celebration of new yam festival.
2. Garri
Garri would pass as the king in the land of Nigerian dishes, as it is a household food in almost all Nigerian homes. There is a popular joke in Nigeria that, though Garri has no advert placement, yet, it sells more than other food products that advertise.
Garri is prepared from cassava tubers that have been fermented, but the tubers must undergo peeling, washing and grating into a mash prior to being fermented. The product gotten from this is then roasted and pounded to form fine flour.
Garri when mixed with hot water, becomes ‘Eba’, and can be served with almost all kinds of stews and soups. It can also be eaten with beans or as a snack.
