BCl3 is an inexpensive electrophile which induces the borylativecyclization of a wide range of substituted alkynes to regioselectively form polycycles containing synthetically versatile C(sp2)boronateesters. It proceeds rapidly, with good yields and is compatible with a range of functional groups and substitution patterns. Intermolecular 1,2‐carboboration of alkynes is also achieved usingBCl3 to
