Ab initio study of the (5R)- and (5S)-TT pyrimidine h5(6-4) pyrimidone photoproducts. Implications on the design of new biologically relevant analogues.

Abstract

A computational study of a series of N(1)- and/or C(6)-alkyl-5,6-dihydrothymine diastereomers at theory levels up to MP4(SDTQ)/6-31G//HF/6-31G and MP2/6-311G//HF/6-31G has demonstrated the respective importance of the substituents at positions 1, 5, and 6 on the energetically favored conformation of each isomer. Results obtained both in the gas and… (More)
