✦ Synopsis

The structures of 1-formylhexahelicene (1) and 1-acetylhexahelicene (2)

were determined by X-ray structure analyses. In the crystalline state, both compounds have conformations with the smaller group of the substituents (H i n 1, 0 in 2) directed to the centre of the helicene system. n-SCF-force field calculations predict that these conformations are the most stable ones of the isolated molecule as well.

We have now investigated the reaction of TPA with compounds containing several hydroxyl groups in various configurations and of differing functionality; for example, the 9-(p-D-furanosy1)adenine derivatives ( I ) , ( ), (5), and (7). According to Mitsunobu, reaction of adenosine ( I ) with TPA affo
