A variety of chromeno[4,3-c]isoxazolidines were prepared in good yields through visiblelightpromoted Chan-Lam reaction and [3+2] cycloaddition cascade reaction in onepot. Mechanistic studies showed that visiblelightpromoted both Chan-Lam reaction and cycloaddition. The obtained products were converted to various useful chromenone derivatives. Moreover, the reaction was easily performed at gram
