A photolabile carba(dethia) malonyl N ‐acetylcysteamine derivative was devised and prepared for the trapping of biosynthetic polyketide intermediates following light activation. From the lasalocid A polyketide assembly in a mutant strain of the soil bacterium Streptomyces lasaliensis , a previously undetected cyclised intermediate was identified and characterised, providing a new outlook on the timing of substrate processing.
