Claims (12)

1. A compound according to structure (4gg) or (4hh):

wherein R2 is any one of hydrogen, acetyl, isobutyryl or triethylsilyl (TES) or

R2 is —C(O)alkyl, where alkyl is from C1-C6 unbranched or branched, saturated or unsaturated hydrocarbyl group that may be unsubstituted or substituted with one or more halogen atoms, or

R2 is —C(O)cycloalkyl, where cycloalkyl is saturated C3-C6 cycloalkyl hydrocarbyl group that may be unsubstituted or substituted with one or more halogen atoms, or

R2 is triethylsilyl or tert-butyldimethylsilyl;

wherein R3 is any one of hydrogen, acetyl, or isobutyryl, or

R3 is —C(O)alkyl, where alkyl is from C1-C6 unbranched or branched, saturated or unsaturated hydrocarbyl group that may be unsubstituted or substituted with one or more halogen atoms, or

R3 is —C(O)cycloalkyl, where cycloalkyl is saturated C3-C6 cycloalkyl hydrocarbyl group that may be unsubstituted or substituted with one or more halogen atoms;

and wherein R10 is any one of hydrogen, acetyl, trifluoroacetyl or triethylsilyl (TES); or

R10 is —C(O)alkyl, where alkyl is from C1-06 unbranched or branched, saturated or unsaturated hydrocarbyl group that may be unsubstituted or substituted with one or more halogen atoms, or
