Thiourea‐organocatalyzed Michael additions of diethyl malonate to various heteroaromatic nitroolefins (13 examples) have been studied under high‐pressure (up to 800 MPa) and ambient pressure conditions. High pressure was conducive to enhanced product yields by a factor of 2–12 at a given reaction time, high reaction rates (reaction times were decreased from 72–24 h down to 4–24 h) and high enantioselectivity
