Absolute Stereochemistry

A highly diastereoselective total synthesis of (+)-pseudohygroline (1) starting from D-proline is described using Wittig olefination and MacMillan-α-hydroxylation as key reactions. (+)-Pseudohygroline is an important molecule in alkaloid chemistry as it was prepared as part of the first chemical proof of the absolute stereochemistry of biosynthetically important (+)-hygroline (2) and (+)-hygrine (3).
