Alkenes can be converted to alcohols by hydroboration‑oxidation. Draw the structure of the alcohol or alcohols formed in the rea
ction sequence. Clearly indicate stereochemistry by drawing a wedged bond, a dashed bond and two in‑plane bonds per each chiral carbon. Draw hydrogen atoms that are connected to wedge‑and‑dash bonds.
1 answer:
Hydroboration-oxidation is a reaction which follow anti markonikov orientation.
The stereochemistry of hydroboration-oxidation follows syn-adition being a stereospecific reaction. That means that boron and hydrogen are added from the same side. Then, when the oxidation occurs, the boron is replaced by an hydroxyl having the same geometric position.
