Two 2H-chromenes having a fully substituted benzene ring, 8-chlorocannabioreichromene (1) and mycochromenic acid (2), were synthesized by a condensation of salicylaldehydes with isopropylidenemalonate or the thermal cyclization of corresponding propargyl ethers.

The total synthesis of methyl alectorialate (3) and methyl barbatolate (4) has been achieved, and the synthetic esters have been compared with naturally derived material.In addition alectorialin (decarboxylalectorialic acid) (5) and barbatolin (6) have be
