3-Substituted (Z)-4-hydroxybut-2-en-1-yl acylates were regioselectively obtained in 2–98% yields by acylations of the corresponding 2-substituted (Z)-but-2-ene-1,4-diols with 10 equiv of vinyl acyl...

The first general catalytic and highly stereoselective formation of (Z)‐1,4‐but‐2‐ene diols is described from readily available and modular vinyl‐substituted cyclic carbonate precursors using water as a nucleophilicreagent. These 1,4‐diol scaffolds can be generally prepared in high yields and with ample scope in reaction partners using a simple synthetic method that does not require the presence of
