Please write the full 3 step mechanism

Amb acid has been isolated from fungi that grow on economically important plants found in the rain forest. Ambuic acid is active in several other tongi that are harmful to these plants, indicating that it may provide chemical protection. During a synthesis of buicaod.compound 1 was reduced to compound 2 using Nahe (Tetrahedron Letters 2005.46 3045 3048) OH Many RO NOBH RO HO OG OH OH OH Me 1 RO 3-0--- 2 Ambuland Me Correct. Two curved arrows are used to show hydride delivery to the electrophilic carbon atom of the carbonyl (C-O). Note that the tail of the first curved arrow is placed on the bond between B and H (it is NOT placed on the negative charge) Add any remaining curved arrow(s) to complete the first step of the mechanism. Modify the given drawing of the product as needed to show the intermediate that is formed in this step, with close attention paid to stereochemistry. Use the single bond tool to interconvert single and double bonds. HET HG HE 104 CH Incorrect Provide curved arrow(s) to show the second step in the mechanism.
