(2E,6E)-farnesyl diphosphate = DELTA6-protoilludene + diphosphate
1,11-ring closure of (2E,6E)-farnsyl diphosphate yields a highly reactive trans-humulyl carbocation. A 1,2-hydride shift followed by further ring closures results in the protoilludyl cation, which undergoes a final deprotonation to give DELTA6-protoilludene

(2E,6E)-farnesyl diphosphate = DELTA6-protoilludene + diphosphate
in the presence of Ca2+, DELTA6-protoilludene synthases catalyze diverse cyclization reactions. DELTA6-Protoilludene and (E)-beta-caryophyllene result from a 1,11 cyclization of (2E,6E)-farnesyl diphosphate following metal ion mediated ionization. The intermediate trans-humulyl cation may undergo a hydride shift followed by two cyclizations and a deprotonation to yield DELTA6-protoilludene.

in the presence of Ca2+, DELTA6-protoilludene synthases catalyze diverse cyclization reactions. DELTA6-Protoilludene and (E)-beta-caryophyllene result from a 1,11 cyclization of (2E,6E)-FPP following metal ion mediated ionization. The intermediate trans-humulyl cation may undergo a hydride shift followed by two cyclizations and a deprotonation to yield DELTA6-protoilludene.
