It has been demonstrated that a wide variety of cyclic tert-beta-nitro
alcohols can be efficiently cleaved regioselectively using stoichiomet
ric amount of NaBH4 in organic solvents like dry MeOH, Et2O, CH,CN etc
. giving open chain secondary nitroalcohols such as RCH(OH)(CH2)(n)CH2
NO2 where R is alkyl, aryl etc. and n=4,5, etc. The utility of this re
action has been demonstrated by achieving short syntheses of naturally
occurring (+/-)-tridecan-12-olide and (+/-)-9-tetradecanolide.
