Synthesis of (+/-)-Lasubine I and II and (+/-)-Subcosine I

The first total synthesis of lasubine I and II and subcosine I has been achieved.A crucial step of this synthesis involves thermal dipolar cycloaddition of 1-(3,4-dimethoxyphenyl)butadiene with 2,3,4,5-tetrahydropyridine 1-oxide, affording the E and

Synthesis of (+/-)-Lasubine I and (+/-)-Subcosine I

(+/-)-Lasubine I and (+/-)-subcosine I were synthesised by a route involving as a key step a 1,3-dipolar cycloaddition.
