  Microwave-assisted Rh–diphosphane-complex-catalyzed dual catalysis is reported. This cooperative process provides [2+2+1] cycloadducts by sequential decarbonylation of aldehyde or formate and carbonylation of enynes within a short period of time. Various O-, N-, and C-tethered enynes were transformed into the corresponding products in good yields. The first enantioselective version of this microwave-accelerated

  The reaction of enynes with acetyl-masked aldoses in the presence of a rhodium(I) catalyst resulted in cyclocarbonylation, thus avoiding the direct use of carbon monoxide, to afford bicyclic cyclopentenones. In rhodium catalysis, aldoses serve as a carbon monoxide equivalent by donating their carbonyl moieties on the acyclic aldehyde form to enynes. A variety of aldoses, including d-glucose, d-mannose

  在铑（I）催化剂存在下，烯炔与乙酰基掩盖的醛糖的反应导致环羰基化，从而避免了直接使用一氧化碳，得到双环环戊烯酮。在铑催化中，醛糖通过将其在无环醛形式上的羰基部分提供给烯炔而充当一氧化碳当量。可以使用多种醛糖，包括d-葡萄糖，d-甘露糖，d-半乳糖，d-木糖和d-核糖，作为羰基来源。使用该方法，各种烯类都以22-67％的收率被环羰基化。不对称变体也以中等至高对映选择性进行。

  With aldehydes as a CO source under solvent-free conditions, rhodium complex efficiently catalyzed an intramolecular carbonylative alkene-alkyne coupling (Pauson-Khand-type reaction) and various bicyclic enones were obtained in high yield. Experiments under argon flow and a C-13-labeling experiment suggested that almost no free carbon monoxide was generated in this reaction, When noncationic rhodium complex with chiral phosphine was used as a chiral catalyst, the reaction proceeded enantioselectively to give various chiral cyclopentenones in up to 90% ee under solvent-free conditions.
