Phosphine-catalyzed enantioselective γ-additions of rhodanines to allenoates have been developed for the first time. With the employment of chiral cyclohexane-based phosphines, a wide range of substituted rhodanine derivatives containing tertiary chiral centers were constructed in good yields and high enantioselectivities.
