Got this from a Colorado State website:
In general, leafy vegetables are the most shade-tolerant, while those that fruit from a flower (tomatoes, peppers, squash, eggplants) are the least. In between are the root vegetables requiring at least a half day of full sun: potatoes, beets, carrots and turnips. Shade tolerant leafy vegetables include lettuce, spinach, Swiss chard, arugula, endive and radiccio. Broccoli (and its relatives -- kale, kohlrabi, turnips, mustard and cabbage -- also grow in partial shade.
