The benzoxazinones 2-ethoxy-4H-3,1- benzoxazin -4-one (1a) and 2-(trifluoromethyl)-4H-3,1- benzoxazin -4-one (1d) inactivate chymotrypsin. The inactivation is stoichiometric and proceeds with rate constants of 7 X 10(5) M-1 min-1 and greater than 4 X 10(6) M-1 min-1, respectively. The inactivated enzyme
