Bring water to a boil for pasta, salt water and cook pasta just shy of al dente.
While water comes to a boil, heat extra-virgin olive oil over medium to medium-high heat. Add anchovies and melt into oil. Add tomatoes, onions and garlic to the pan, season with crushed red pepper flakes, oregano, parsley and pepper, saute until the tomatoes and onions are soft, 8 to 10 minutes.
Add wine and reduce for 1 or 2 minutes, melt butter into sauce and add clams to pot. Cover the pot and cook clams until they open, 6 to 7 minutes.
Remove any unopened clams and add pasta to the pan. Toss linguini with sauce for about 2 to 3 minutes so the pasta absorbs the flavors. Add basil to pasta and taste to adjust seasonings.
