Sequential Condensation Reactions

Part 1
Many useful synthetic procedures involve sequences of aldol, Claisen, Michael and Mannich reactions. The following equations describe a few examples. Consider each reaction in turn and try to write a mechanism for the transformation.
By clicking on an equation a plausible mechanism for it will be drawn in the space on the right. Electron pair shifts are designated by magenta arrows.
