In most of the methods of public key cryptography devised in recent years, a finite field of a large order is used as the field of definition. In contrast, there are many studies in which a higher-degree extension field of characteristic 2 is fast im

It was observed that the synthesis of tricyclo[5.2.1.01,5]decane 10 can be performed effectively by the intramolecular double Michael reaction of 5-(5-methoxycarbonyl-4-pentenyl)-2-cyclopenten-1-one (9). Highly stereocontrolled total syntheses of (±

Total synthesis of (±)-cedranediol ( 7 ) was achieved using intramolecular double Michael reaction. Heating the enone 10 together with ZnCl 2 , Et 3 N, and TMSCl gave the tricyclo[5.2.1.0 1,5 ]decane 9 as a single diastereomer, which was converted i
